Hello Everyone

Looking to see if the following will fit with no guard work

Font & Rear : 18x8.5 +30

i would prefer if it wasnt too flush. i definitely dont want it to stick out... i spent the last 15 minutes viewing the first 20 or so pages and i coudnt find it... so please advise me thank you.

I dont know what tyres i have atm, just goin to switch my tyres over... only owned this rx8 for about 6 months

stock suspension. and i do not plan on lowering it, i cant afford to nor do i want to with all the hills/bumps here.

 

will 18x9.5 +35 fit all the way around with 225/45 18 without rubbing? no drop yet but was going to do S techs

 

Don't do it

 

Look for something closer to 8.5 +40.

 

Is there a question in here somewhere?

thanks
J

 

you can fit 10's with no rubbing on stock fenders, all depends on offset man, +0 will rub like crazy but +40/50 is an easy fit with wide tires.

 

Should I change tire size or just stay away from the whole idea?

 

Yes wider tire and don't put them on before lowering it. 245/40 at the least. http://www.flickr.com/photos/j863562...7611482633008/ 9.5 +38 with 245/40 and a similar drop to s-techs

 

do u think there would be any rubbing issues?

 

at 245/40.....no. Wider than that....maybe

 

looking to get Rota p45r's on my 2004 rx8 (stock height currently). im looking to get 18X9.5 with offset of 30mm and some tires that are 245/40. will this be ok? i will be dropping the car as well, but nothing crazy. just .5 inch to 3/4 inch. any help would be appreciated. thanks in advance.

 

You will be herrafrush at 9.5 + 30. With a big drop you would definitely be rubbing. Even with a mild drop you will most likely rub under aggressive cornering.

 

I think a +38 or more you'd be fine.

 

I never rub running 18 x 9.5 +30 with 245/40-18's dropped on S techs and KYB gas adjusts. Shocks matter.

 

Yeah when he mentioned mild drop I assumed he would be running stock shocks just changing springs. Could be wrong though, wouldn't be the first time.

 

I would suggest closer to +40 as well.

 

What would be the best offset for a 10" wide rim and trying to run 285 rubber?

And will 18 x 10 + 38 fit?
what would be required to make them fit?

Thanks

+38 offset

 

I hope you are one of those parking lot racers if you want 285s. That's a huge tire.

 

People you must post your suspension for someone to help.

 

Seriously?

 

Car will be driven on the track a fair bit and occasional weekend drive. Suspension is adjustable of course.

 

almost certainly too much tire for the track. 245s are more track oriented

 

How so I always thought, wider tyre = more grip?
