I already have my Cooper STT Pro tires sitting in my garage (305/70/18). I been waiting for my stock tires to wear down. Now im at 3/32 of an inch on my stock tires and gonna install the Pros. These tires are a true 35". Should I use wheel a 1.25" wheel spacer to change my stock offset from +60 to +30 to help with possible rubbing? BTW 295/70/18 is on national backorder so I just went with the 35s.
