tire and rim size

[dale187]

Ok guys my front tires are about ate up because of a bad alignment issue i had... now it is time for some new rubber. But the thing of it is i love the look of a nice wide tire in the rear. Now the rims i have now are not staggered or anything but i still wanna put a wider tire in the rear.. Whats the biggest tire u think i can go with with a 2.0 inch drop? I'm trying to atleast fit a 245 on it. I'm going to stay with my 225/40/18s on the front and maybe a 245/35 on the rear. Also i have a friend selling some nice gunmetal rims with a machined lip. The fronts are 18x8 with 2 inch lip and in the rear its 18x9.5 with a 3 inch lip.. But the only thing im worried about is yes thats a rear wheel drive thing... do you think it wuld look stupid because its on an awd car? And also would they fit? also do you guys think ### the rim is heavier in the back it will mess up how the awd is functioning? All opinions accepted.. Thanks guys

Do not run staggered rims on an AWD car. Wheel speed will be different and can mess of the transfer case and rear diff.

I would go with a 1.5 - 2 inch drop and run 17x8 or 18x8 all around. With that kind of drop you will run into some negative camber. So please perform a camber kit install on the car as well.

Staggered wheels on AWD/FWD cars look rediculous unless you bolt on a HUGE triple decker wing and zip tie a cracked fiberglass body kit to the car. Make sure the body kit stays forever in primer. There is a myriade of performance and functionality issues with staggered wheels on AWD like mentioned above, dont do it.

go with 17s and put some fat rubber on them. this will give the best traction. dont stagger....you'll look ricey.

i got a question for this thread. will the speed mess up the t/c and rear diff because of the diameter of the tires or the weight of the wheels. because i know you should only run the same diameter on a awd car. but if you put wider tires in the rear with same diameter as the front will they be effected?

 

[rlacasse1]

its the diameter that will cause problems. not so much the width of the tire

You guys think in a straight line too much. Cornering is where it will put the strain on the car the most. And the car will more than likely understeer badly.

Not only that but just because two tires have the same size stamped on the side does not mean they are dimensionally identical. With larger tires (30"+) I have seen as much as 3/4 of an inch difference between brand new tires from different brands with the same dimensions.

It is especially hard to match metric tires because there is no diameter measurement on the tire so you'll have to do math on each tire and there isn't a specific common diameter that manufacturers shoot for. Keep in mind that in many modern cars if the computer senses a difference of as little as 5/16ths of an inch between tires many AWD systems will shut off to keep from damaging components.

Specifically never run different tires on an AWD or 4wd vehicle. Even the same tires wearing at a different rate can be hazardous to the long term health of your AWD system and since DSMs use a viscous coupler you can really screw things up. Once a viscous coupler gets cooked it can lock up too easily and force wheel hop in corners which will literally break axles, joints, and shred tires. Having had that exact issue in a Grand Cherokee I can tell you that it is also incredibly annoying.

well a couple of months ago i was thinkng about going staggered width and i was doing some research on the size and diameters on tires compared to OEM and if u go to the manufactures website like toyotires.com or others and on the tire selected it will tell you the specs and sizes and i found two different size tires with the same diameter that was .01-.05 in off the OEM diameter.

Then get a nice rear-wheel drive car that has to compensate for other chassis shortcomings, and run them on it.
