dumb question...run 3 17" rims and one 15"?? (pot hole got one of the 17"s)

[Cygnus_X_1]

k...so i cracked the lip on one of my 17"s (good old jersey potholes) and need to get it fixed. how safe/unsafe is it to run three of the 17"s, and one stock steel 15"? or should i just run 2 15"s (either back or front but the cracked one was on the back) and 2 17"s? last scenario...jsut run all stock 15" steelies till i get up off my lazy *** and get the rim fixed...

I am not sure if it applies to our cars, but a friend of mine ran 3 dazz matiz rims and one stock rim on his gsx... long story short he ruined his differential (s)

You need to make sure the tire's overall diameters are close if not almost exact.

The reason the GSX cannot do this is because you'll have one wheel spinning at a different speed than the others. Revolutions per mile differ. You should never ever run different sized tires on the driven axle of a car or truck.

For example, many(all that I can think of) modern AWD cars specify in the owner's manual that you cannot have more than 2-4/32" tread difference between any of the tires. If you blow out a tire on a subaru AWD, you cannot replace just one tire.

If your tire OD is identical between the steelie wheel/tire and the 17" unit, run the single steelie on the front. OR, just to be on the safe side, run two steelies on the same axle. The key for a 2wd, and rwd, is to keep the same rolling circumference on either side of a given axle.

so it looks as if to play it safe, i will run dori dori style...lol

why not just change the whole set until you get it fixed? swapping wheels takes less than a half an hour.

Smith SR is correct, the key is O.D. on the tires. If you take it easy and don't get too crazy you could limp by for a while with the one odd ball tire/wheel but it would make more sense to switch them all out if you have the spare set of tires/wheels.

<-full sized gram light spare

hah.I really cant add anything, except if the OD is the same(within 4%) you sohuld be OK short-term.

with any AWD you cant have nearly any difference, one reason I hate jeep:THE AWD jeeps had a dummy spare thats both too narrow and too high.....which in 5 days will wax the diffy in the vehicle, yet jeep claims "its fine"....
