Why the different sized tires on front from back? There is no reason to get the same sized rims and then get different sized tires. https://www.rx8club.com/rx-8-multimedia-photo-gallery-6/polaks-im-going-take-pretty-pictures-my-car-thread-119913/ I have the same rims with 245s (didn't know I was getting the rims or I would have gone 255), but I won't have them mounted until Monday.

Your car's awesome mate.
I was hoping someone else had these wheels cause i went to the tire place and they said they weren't going to fit and tried to get me to buy some of there shitty mags after i just got my rays.
um the different tire size i just got recomended that.
You reckon i should go 255 all around?
Thanks Nathan.

You'll need a slight roll in the rear.

255/40/17 on a 8.5" wheel?

imput1234

iTrader: (6)

Yes, it'll fit as long as that wheel is also 17".

I hate to ask but will this fit: 20in, width 9.5J, bolt 5 x 114.3, and offset 45 without any modifications? If so, what is a recommended tire size?

imput1234

iTrader: (6)

Why 20's? Are you lowered? if you are you may have a problem

a tire that is 25.9" in dia. should work like a charm. all the way to 275.

this may have already been answered but i am thinking of running this combo for wheels and tires also i have the mazdaspeed lowering springs .5-inch and the stiffer springs from them too:

18x8.5 +40 - 245/35 tires
19x9.5 +35 - 275/35 tires

i am currently running:

18x8.5 +40 - 235/40
18x9.5 +35 - 265/35

no real problems didn't have to get the fenders rolled but when the car is loaded (people,groceries) there is a slight rub in the rear but only when i go over bumps and stuff.

Any help on the new combo is appreciated

You will need to roll the rear, but negative camber should help you clear as well.

MS springs are a .8" drop, and that .3" could really matter. You had 265s in the back and they only rubbed when loaded down and big bumps? Nice. I have 9.5" +38 and I wasn't wanting to roll the fenders just yet.

hi im running with 18x8 225/45/18 bought aftermarket rims but same size with stockies. now i bought sprint springs 2" drop will i rub?

imput1234

iTrader: (6)

yup, no problem.

imput1234

iTrader: (6)

What is the offset? Since your running OEM width, chances for rubbing are slim to none, unless you are running a uber low offset/

rx8bb6evo8

iTrader: (-1)

oh yeah... im using +35 offset.... thanks!

anyways u guys are more pro than me so i'll take ur advices!

thanks!

^If u wanna look at the drop from the spring, look at my spring thread, its a sticky in the picture section

18x8.5, +29 off, lowered 1.5" on tein basics.
i was thinking of 235/40/18.
what are opinions on the fit or needing a roll?

imput1234

iTrader: (6)

Yeah, you may need a slight roll, but you could just add more - camber.

jerseysentra

ok thanks, i might try getting a 225 40 18 as well. i have a pretty decent amount of neg camber now anyway, i was running an 18x8.5 +37 in back with a 265 35 18 and never had a single rub

Can someone tell me if 245/40/18 will fit on the stock rim? Is this the widest you would want to go on stock?

J8635621

iTrader: (10)

245/40/18 definitely fits. It is very common. According to some other threads, 255s will fit as well.

imput1234

iTrader: (6)

Yes.
