Thanks. But I think PaPaHoFF has the cleanest AWD on the site that I have seen.

For anyone who have ran or know someone who ran
19/35/225 Front 19x8.5
19/35/245 Rear 19x10
Was there any major problems with this setup? I was planing on running this setup for a little stretch in the rear and was concerned if this was going to mess anything up. I put this into the 1010 tire calculator and the rear difference is about 3.03. Is that a big difference or should it be fine? Any input would Help !

IS2FIFTY you can only be 1% off on the rolling diameter other wise there goes your awd system. You can run 225-35-19 front and 255-30-19 rear.

I was thinking of going with the same one as well. Please post some pics when you install them.

Hey guys, I just ordered some Concept one rs-8's with the following specs:

19x8.5 - 38mm (f)
19x10.5 45mm (r)

I do realize i will have to do some fender mods. I was wondering what tires i should run to have the closest rolling diameter. I used 10/10 tire calculator but Im not sure about tire stretching etc. I really appreciate it, im going to buy tires based on your advise most likely.

I know I can run 225/35 front s but What do you recommend for the rear? 255/35 or 265/30? I think 255 is closer to diameter but doesnt that mean more stretch? Im trying to stretch the tires as least as possible

Will having the overall diameter of the wheels bigger than factory 17's cause any transmission problems?

would the following tires work for 19x10.5 +22 and 19x11 +23? I have a feeling these wheels are too wide...

235/35/19
275/30/19

That way to wide to go up front. Your best bet is to run 19x9.5 up front and 19x10.5 rear. Ive seen the 19x11 fit but you gonna need a good shop to pull the fender or more to fit it.

Is it too wide if the car's not lowered?

i would like to reduce the gap between my fender and my tires on the back maybe on the front also but its not too bad

here is my set up

rims
19x8.5 offset +35 front
19x9.5 offset +38 back

tire

front 225/35/19
back255/30/19


lowering spring h&r awd (11/4 inches drop)

Question is can i put 265/30/19 to reduce the gap without rubbing, will it make a difference

with this set up the car is wobbling when i start until 50mph.

This thread has been very helpful.

Can someone confirm if the following setup will rub or not? The car is not being lowered at the moment

19x8.5 +35, 235/35/19
19x9.5 +35, 275/30/19

Thanks!
