im getting some 19x8.5 on the front and some 19x10 on the rears my question is: would a +25 offset push the tire out further than +38 offset?

 

which one is +25 and which is +38?

 

yes, by 13mm, and those won't fit on an FD with stock bodywork. The +38 will work (not the best) on those wheels but you would have to roll both front and rear fenders. Tire availablity is EXTREMELY limited in 19" sizes to fit the FD and I don't recommend it. 18" allows for a lot more choices.

 

i guess what im asking is: which offset pushes the wheels our further a +25 or a +38, a +30 or a +45? does a higher # mean more pushed out or does a lower number mean more pushed out. im just speaking hypothetical.

[B]this is what i am getting: (5ZIGEN)

19x8.5---front
+25 +38 +45 5-114.3 with 255/35/19 tires (front)

19x9.5---rear
+25 +38 +45 5-114.3 with 285/35/19 tires (rear) with the burnout kit rear fenders.


so please tell me which one of these offsets would go with the front and which would go with the rear. im not changing the tire sizes and i like those rims thanks, this is very important because i have to order these rims right away.

 

Lower number is further out. Higher number is further in. For reference, stock rims are +50.

 

ok so a +45 in the front and a +25 in the rear with the burnout kit fender flares? does that sound right?

 

+45 is perfect in front

 

So, you'll be running stock front fenders? If so, those offsets will work....

Your tire sizes will NOT work at all. On a 19x8.5, you can fit a 255 (not ideal though), but the size should be 255/30, not 255/35. For the rear, a 285/35 will be 2-inches taller than stock tire diameter....not good. A reasonable diameter could be achieved with a 275/30 19. Running a 285/30 19 will be an inch taller than stock, which will raise the final drive quite a bit.

 

How far the wheel sticks out depends on BOTH the width and the offset.

For a given wheel width, +25 offset will stick out more than +38 offset.

For a given offset, a 10" wide wheel will stick out more than an 8" wheel.

And when considering stick-out-ness, you have to consider what you are comparing relative to. I don't know if the stock wheels (which are 8" wide and +50 on front and back) stick out the same amount relative to the fenders in the front and back, but I doubt it. Alignment will certainly affect how far the wheel sticks out relative to the fender as well.

It's easier to make the comparisons relative to the stock wheels, since you can easily calculate that a 10" +38mm wheel will stick out (10" - 8")/2 + (50mm - 38mm)/25.4mm/inch = 1.47" more than the stock wheel, assuming the same rim lip width (which does vary, but these are often the only specs available to calculate with). If you have some stock wheels you can use to use for relative measurement (to determine how wide you can go), this might be the most useful frame of reference. But it still may not be perfect, since running wider wheels often means that the optimal camber is closer to 0 than it is with skinnier wheels.

Master wheel sizing. Make it your bitch, so you don't have to be a slave to its mystery. It isn't hard, it just takes high school algebra and a little focused effort. You can do it.

but it would work though right? i could get some coilovers to lower the height if necessary the tires are already here and it would be more trouble than its worth (i think) to send them back and have a different kind sent.

 

update: i just emailed my tire sponsor and they are going to take care of everything for me and switch out the tires. thanks guys.

 

ok the only size tires they got will be: 245/35/19 front and 275/35/19 rear. (no 30 series) in those sizes. thats it. done. finale. thanks again guys.
