245/40 but you could probably do a 265/35 if you roll the fenders

 

Use this link to help you figure out what kind of offset you want to run. It helped me a lot.

Wheel Offset Calculator

 

thanks J#'s.

 

ok wanted to know if these wheels would fit on my Rx8.

18x8

Wheel Diameter:18.00 in / po

Wheel Width:8.00 in / po

Bolt Pattern:5-114.3 mm

Centricity:LugCentric


also wanted to know would i be able to fit 225/40/r18 tires on that?

not good with this kind of stuff so please let me know.

 

Not enough info (offset). Why shorter tires than stock? Suspension mods? I'd suggest at least 18x9 if you are buying new wheels.

 

agreed. Why replace the wheels with ones of the same width? The stock 18's are so nice.

 

the wheel i want are only made in 18x8 then it jumps to 20x9

 

so get a different wheel.

 

been hunting them for 2years the only ones i like :P what are the stock seize? and whats the max offset i could go on those wheels? that i posted some specs

 

with 18x8's? You could probably go like +0 and be safe hahaha, And what wheels?

 

stock size is 18x8, offset is +50

 

Can anyone tell me how rough an 18x9.5 +20 all around is gonna be with 255/40s?

On S-techs and saving for coils.

 

245/40 is mucho bettero

 

That was my initial thought but saw an awesome closeout in the other size.

 

Oh sorry, it's an xxr goofy 18x9.75

 

Roll all around and remove tabs. Not the look I go for but others have done it

No 255/40 when lowered. All kinds of extra problems.

 

Thank you sir.

 

18x9.75 +25 w/245/40 (huge tires)







We eventually put 265/35 n' it squared up the stance pretty nicely but caused some rubbing issues. You'll need to work on grinding down the bumper tabs and relocating them if you wanna keep that bumper from flapping. It is easily possible if you get the right tire and dial in the suspension and get creative with the camber/toe work.

 

What have you done tab relocation wise, atilla?

 

I already ordered some 245/40s after Jnumerication's words of wisdom. Tirerack had some very sticky-icky OE Mercedes Dunlops in a 255/40 on a closeout. $135 instead of $305.

 

Yeah - i pulled a rev n' relocated the rear bumper tabs further back along the rear bumper mounting point (a couple of inches away from the oem mounting point/rubbing point). I drilled a new mounting point thats being secured by a beefier grommet and two automotive grade clips on each side.

 

I'm gonna get mine on and see how far I need to go with everything. Good thing it gets less than 100 miles a week put on it.

 

will 18x9 +35 fit all the way around on stock height? what's the biggest tire you can fit on a 18x9?

 

18x9.5: Not sure if I should go with +38 or +35?
245/40/18 tire: Is that large enough?
Stock Height.

 

Those offsets are close enough to not really make a difference. That tire size is okay but with a +35 you can fit a lot more. It may look a little goofy at stock height, though.
