OK, this will show they're staggered... 10" out back.

huh? dont understand what ure trying to say here..
ur not saying that u can fit a 40 tire using 20s ru?...

I've made up my mind.. im gonna go with 19x8.5 +35 all around with 245/40/19 tires... then once a camber kit comes out ill go with staggered look.. =)

BITKAHUNA - nice!!!! you think ull be able to put a 19x95 or 19x10 in the front so ull have dual lip action?..

OK, but the rears will be inset which I don't care for (could do H&R spacers though maybe). Are you worried about early tire wear in the back? If so, you should be more worried about it in the front.

You can't put 9.5 or 10" rims in the front and I have no interest in such heavy rims up front anyway, plus I wanted big front brakes so I only get a 1.5" lip there (although it looks a bit less because of the high disc fitment). You can get a 2" front lip with high disc though. My rear lip is about 3".

im worried about tire wear in the front.. and what do you mean by inset? is it when the wheel is too much in the car like how it is stock? but isnt the +35 offset aggresive enough?

what determines the size of the lip? the width of the rim? the "disc"?
what would it take for me to get a 3inch lip all around?

Yes, by inset I mean the outside face of the wheel/tire sits too far in the wheel well and doesn't have that nice 'flush' look. BMW and Mercedes achieve that with the factory sport packages because the rims are staggered.

My 8.5" front rims are +38. I've never tried putting one of them on the back but I bet it would look inset. A +35 you're considering is only 3mm ( .12 inch) further out. The look does depend some on the wheel design though - flat spokes like the factory 17s don't look THAT inset but if you're going for a huge lip then they will look even more inset.

(4 questions there, hehe.) Size of the lip is determined by the offset and rim width mostly I'd guess. I'm no expert but that's never stopped me trying to answer questions, LOL. As far as I can tell, the high, medium, or low disc fitment is really about how much the spokes curve outward from the rim center before curving back toward the outer. The fitment allows or doesn't allow bigger brakes behind but more importantly it changes the look of the rim. It's a trade off. Low disc rims make the lip look HUGE (even though it isn't really any bigger as far as I know). High disc makes the lip look smaller because the curving of the spokes tends to hide the lip some (as you can see in the pics of mine up front). But offset, rim width and fitment all interact so there's trade-offs.

This article about offset might help:

As far as getting a 3 inch lip all around, I don't know if that's possible. GSTRANCE has the largest front lips I've seen on Zauber Gettin's. Looks awesome.

OK how bout this scenario.

19x9.5 rim in the back with +45offset and wrapped in 275/40/19?

will this rub?

i want to go 40 all around if possible

245/40/19 in the front with +35offset 19x8.5 and 275/40/19 in the back with +45 offset 19x9.5.??

or is it better to do it like BITKAHUNAs setup?

I have a feeling the front is going to be an issue. Sorry I don't have time to figure out all the numbers to be sure. I'm sure someone else will chime in.

nah you can run a 265 on a 8.5... i run 255s on my 17x8s right now
it really depends on the sidewall height

bitkahuna

Mine are 275/35-19 with +42 offset and it rubs if I hit a deep dip at some speed or go over a speed bump too fast. I think mine might be more a suspension travel issue than wheel/tire size, but I guess it's all the same.

WHY? the '40' is a *percentage* you know, right? 40 is the percentage of the width that the sidewall height is. So 40% of 275 is a whole lot bigger sidewall height than 40% of 245.

Why do you want to do this instead of 35 series on the back?

Bean says you can run 265 on 8.5" rims and that might be possible, but you DON'T want to put 265's in the front wheel wells - I'm almost positive they'll rub a lot, no matter what offset you have.

well depends on how low you go. i know that 8.5 +32 will still work with very little rubbing. so i guess +35 will give a lot more room

rominl

you can't run 275/40/19 in the back.... you have to do 275/35/19. the sidewall would be the same as the front in 245/40/19

Sorry. When I read that he wanted to go 40 all around wiht 9.5 in the rear, I somehow assumed he wanted to go 9.5 all around. My concern was for 9.5s in front. My bad.

rominl

iTrader: (4)

bit you are right on, 40 is the aspect ratio, not a direct measurement. and +45 would be very good. my 19s are 9.5 +38 in the back and i never rub. bit, yours is 10 so +42 that's a lot tighter than 9.5 +45

and bit is right again too, mounting 265 in the front is like suicide, not only rub, i wonder if it will even hit the suspension. and technically from what i read, 245 on 8.5, 275 on 9.5, these are the best setup

What is the recommended psi that i should run with 245/40/18 tires to get maximum protection? I always tought that it was like 33psi.

rominl

iTrader: (4)

well i am not sure if there is a definite "minimum", but if you want to protect the rims more, more pressure is better. on my 19s i always have like 44psi on it. the stock 17 it's like 32psi, so if i have 18, i would probably put something like 38 to 40
