what are u biggest rims i can get witout voiding my warranty....

 

any size!!!!!! I dont think warranties cover rims

 

Huh? Rims dont affect anything, I dont know who told you otherwise. Buy away!

 

19s

 

I don't think it would be the greatest idea to put 19's, or even 18's on the car. You'd be riding on such thin rubber at that point, one pothole and it's over for you. When my car comes in, 17's will be my choice.

 

17's are DEFINITELY my choice also, especially with all the potholes around here in Chicago...

 

i could have sworn i was told that 18's and over voided warrenties

 

i thought anythin above 18's would void ur warranty or somethin like that i really want to get 19's but i'm scared that if i get them the junky dealership i got will rape of my warranty....

 

My scion dealer said any non stock/or TRD wheels that are offered as optional are not covered. So you can get 18's or 19's but they have to be the TRD's or the Enkeis. You can fit 20's you just need a super small tire. Nitto makes a good one.

 

I wouldn't go 20's. Or even 19's really. Unless it's a show car, or you only drive on marble streets.

 

18' any bigger size in my opinion decreases ride quality

 

Tire Rack offers trouble free/rub free options up to 18" for your xB!
