SCCA SM2 Tire Choice: FD w/ Stock Wheels

RX7Club,

After looking around for potential racing wheels, it's starting to look like the OEM wheels are the right choice because they are lightweight and cheap. My question now is, what is the best size tire to throw on here? I am looking for something wide and available. Generally, wide tires are not offered in 16". What do you all recommend for an R-comp SM2 reasonably competitive tire that works well with the OEM platform? What do you think of Victoracers in 245/45ZR16 and 265/45ZR16. I think victos because they are streetable.

Thanks!

-Jake

FYI, the top FD SM2 guys are in the 285 tire range.

if you must stick with the stock wheels, 245/45 would be my suggestion. Sometimes its not how much rubber you can fit on a wheel, but how well it fits the wheel to make it perform. Grassroots motorsports has had many tire shootouts with R compounds and have found that right sizing versus oversizing actually yields great results. I use FD wheels with 225/50's on my FC and it worked really well considering I drive through a poorly put together suspension (my fault entirely btw)
BTW since people are going to ask anyways. I am wondering if you are on a tighter budget or something because there are plenty of reasonably priced light weight wheels in FD-friendly offsets available.
Hell, edgeracing.com and tirerack.com are 2 very good sites and have very good deals on wheel and tire packages.
Anyways, good hunting this season

I never buy wheels new. And I rarely buy tires new either. It's a matter of principle not budget. Maybe I should start splurging a little on my FD though. Looking at wheels, buying a larger set just didn't make much sense. FD wheels are so light.

Erik runs 285x18 up front and 315x18 rears, Andy runs 315x17 fronts and 335x17 rear. I will be running 275x17 fronts and 315x17 rears.

If you are using stock wheels you could squeeze a Kumho V710 225/50ZR16, 265/45ZR16 or a Hoosier A6 245/45ZR16.

Both are excellent tires with the Kumho's lasting longer and the Hoosiers having the edge in turn in response.

I'm running Kumho 285/30/18 front and rear.

With Enkei RFP1 (or is it RPF1?) wheels, that's right at $2500.

Staggered setup is a bit more.

No need to start buying new now! Just pick target wheel/sizes/offets and start doing an ebay search routine every time you log on the computer.

I decided I wanted 17x9.5 +35 or +40 Volk TE-37 for the rear of my FC and a couple months of routine search landed me that rear set AND included a the perfect companion17x8.5 +30 for the front (I had thought I was going to stick w/ my 16x8 +30 front TE-37.

Whatever you want is out there and for sale used for less than half of what it would be new- you just have to find it.
