Cheap 18x10 +50 wheel for autox?
http://www.discounttiredirect.com/di...=10&bp=5-114.3
Besides how they look.... whats wrong with these for running 285/30/18 V710's on an FD on all 4 corners for autoxing? A little background: I dont autox for points, or to be highly serious. Purely for fun. I dont go to every event, just when I feel like it. I am rather tired of being beat by nearly every car with race tires just because they have race tires. I am pretty consistantly one of the fastest on normal street tires.(as far as I can tell since its not like the standings mention what brand tire others are running ;) ) Given this, I figure I'm not going to learn a whole lot more running street tires, so I wouldnt mind spending a little bit of cash to get some sticky rubber. What I wont do is spend $1000+ for lightweight expensive 18x10's and then buy race rubber on top of it. Admittedly Id NEVER buy wheels like this for driving on the street. However, 1 event a month and 4-6 runs at each event I cant honestly justify paying high dollar for wheels. Thoughts on these? Any experience with this brand? My only real worry is they weigh like 35lbs, or they are so weak they would bend from lateral loads exerted by 285 wide v710's.... |
Hard to beat the price, that is for sure. I really don't like the way that discount tire doesn't give the weights of the wheels or how they are made. At that price, I'm guess that is both gravity cast and heavy.
The Tire Rack has ASA JH8 18x9.5 ET45 wheels on closeout for $159. 23.8 lbs and low pressure cast. That may be more than you want to spend and it is a tad narrower, but it should (barely) fit according to the nifty Excel spreadsheet. The only racing I've ever done is with running shoes, not tires so I haven't a clue. |
Honestly, I think you'd be much better off getting some V710s in a 245/45 size on the stock wheels.

Does your opinion change if I have 370whp and 355ftlbs? |
By the looks of them brake caliper clearance might be an issue, and they're probably really heavy, hurting performance.
|
theres a few guys runing these already .. dont know about that offset , is that the only offset they come in?
|
ya, considering how i work for that company, those are the most garbage wheels we offer. seriously, save your pennies and get some gram lights, or something light and wide.............................................. ......enkei rpf-1 anyone?
peace |

I'd look for a decent used deal... call Fritz... or just stick with stockers. You'll get most of the benefit of R-compound rubber, even in 245, compared to street tires of a larger size. Won't be as much as w/ 285 race rubber, but you won't pay a terrible weight penalty (which also costs time, in both sheer weight, and deteriorated handling).
You could also consider 17x9's or 9.5's w/ 255/40's or 275/40's... that'll save you some money and the rim sizes aren't quite as rare. |

peace Since you work there, what do they weigh? |
uh, i have no idea, i would have to look when im at work, but i would say at least........................too much. dude, i have no idea, but EASILY twice as heavy as stock.
peace |
i bet they weigh more like 45 or 50 lbs
|
Check out this thread too.

Discount tire direct says 26lbs a piece. I just got off the phone with them.
I told them what wheel and the guy said "thats a great choice for your mustang" lol. |
for $100 bucks a wheel they are hard to beat

You can get a set of Rota Slipstreams in 17x8.5 and run a 255 size (all around) r-comp on them. They are around 15 lbs with a good offset:

I know this is not exactly accurate math, but from the slipstreams to those 18x10s you're looking at 11 more pounds per wheel, 44 more pounds total rotating weight. that's a BIG difference.

But also 30mm per side, so 60mm front, and 60mm rear. I would think that the 120mm more of race rubber would offset the 44lbs of unsprung weight? I dont know, thats just my guessing. Any input into that? |
weight is weight no matter how you cut it. unless you have the power to put down the weight issue, and the brakes to stop that weight from its path to destruction, it wont offset anything.
44 lbs is 44 lbs, thats half a backstreet boy. peace |

Any input into that? it's been said that one pound of unsprung weight is akin to adding anywhere from 2 - 10+ lbs of sprung weight to the vehicle, depending on who you are asking.

in my experience, it's true. in 2003 (my stupid years) i had some extremely heavy axis 17x7 shit wheels on my 240sx that must have weighed 20+ lbs each. one day, i got a flat and had to use my oem 15x6. switching back to stock wheels made the car feel ridiculously nimble in comparison. seriously, i was shocked. i never put those axis wheels back on. |

But also you should know that any good 285/30/18 tires will be well over the cost of those wheels... Some street tires in this size could be in the range of 300-350 a piece ($1200 a set). I recently bought a set of Bridgestone RE050A PP, 285/30/18s for my SSRs and it was as much as what I paid for the rims after I got them shipped and mounted. Overall, I would listen to Rich and stick with stock rims (used set 300-400) and 245/45/16s (pending type of tires, $600-850/set). And since you said you are not going to be competitive in autox, I would just put some cheap/reasonable performance tires on it and just have fun:) If you dial in your suspension and slicks, I bet you'll be pretty damn competitive! Friend of mine here uses stock rims and 245s and did pretty well.. |
lightweight corners > wide tires
|
I've always heard the opposite, sacrifice weight for width within reason. Those who've tested this have found it to be true. 26lbs is not terrible for a cheap wheel that big. I'd still try to find something lighter though.
|
Within reason I suppose, 35lb/wheel is not.

that's an odd question.

cool, another person taking what i say out of context and trying to correct me to sound smart. if you actually read what i said, it is clear what i stated "44 lbs is 44 lbs." if you have graduated high school, which is obvious you have not, you would realize that i stated adding 44 lbs is another 44 lbs of UNNECESSARY weight. now, what you stated was also right, that even thought its 44 lbs, it could feel like alot more. you want to know why 44 lbs of dead weight could make the car feel sluggish.............do some physics on objects in rotational motion, then get back to me.
dont take what i say out of context peace i thought i was being friendly O_O i wasn't attacking your post. i just thought it was a good illustration for bryan downs, and your post didn't really explain the consequences of adding unsprung weight. |
Anyway, according to BryanDowns they're 26lbs, not that bad for an 18x10, especially one of that sort of price.

wheel weights has a non-descript "CCW" at 22 lbs in 18x10.
lightest is buddy club p1 qr at a hair over 16 lbs, which is lighter than the next three wheels which are magnesium. wow. anyway, for general comparison te37's tip in at 19 lbs bbs lm's just over 21 lbs rpf1 "rc's" come in 23.6 lbs |
There are other options.
1) Go with a serious racing street tire, like the RE-01R. You'll get loads more grip and still not screw around with hauling another set of wheels. Don't kid yourself - there is always more time to be wrung out of a street tire, and plenty more to learn. 2) I would not go 18" for autox. I would do wide 17s. But then again you have torque to burn compared to me, so the decision is yours. 17s will turn easier and be less damaging on tires when your alignment is set up for fast autocrossing. Dave |

There is another issue I feel obligated to bring up:
With an 18" wheel and 30 profile tire, your camber has to be *just right* to get max grip in the turns. Otherwise, much of that extra width isn't being pressed to the pavement. So there is a risk that this upgrade may not improve things at all. A 17" rim will give you more sidewall and better tolerate imperfect camber, probably giving you more usable grip. What tires/wheels are you running now? What class are you in? Dave |

What tires/wheels are you running now? What class are you in? Dave Running my street wheels, which are Racing Hart C2 3-piece 8"/9" wide w/ 235F/275R wide RT615s. The reason I was looking at 285 or 275 wide tires is because the price difference (with these wheels, compared to other wheels for not as wide tires) isnt alot in the whole scheme of cost for the combo. I'm running Emod,and while I'm not really out to be "fastest there", I'd like to at least be competitive enough to have fun :) |
In my opinion, 275 width tires on a 9 inch wide wheel isn't a good idea for auto-x. Too much tire for such a narrow wheel.....
|
275 wide RT615s are pretty wide and pretty sticky.
IMHO, only an R-compound is really going to change things. You'll lose a second or two instead of a tenth or two. You could use an RA-1 and drive a short, dry distance to the autox site, but it's probably better to get V710s and not drive them on the street. Dave |
i agree you should just put some 245 (or 265) v710's on stockers. its a good, cheap, effective combination.
too bad you missed out on SSR comps 18x9.5 +45mm from tire rack for $199 each closeout special. thats what i'm running on 285/30's this coming season. |
There's a guy who just put stock sized V710s on eBay. 225/50R16. I almost bought them but my set's hardly worn. These plus stock wheels are cheap, light, fast, and GRIPPY!!
