My 11 justa has 185/65r15 88t tires. Any issue going to a 195/55 r16 87v tire? I know the tire will fit but wasn't sure if dropping the tire load rating to 87 would pose any issues. I assume not, but just want to confirm before I buy

 

88 vs 87 load rating is a difference of 34 lbs, so you are probably fine. And you'd need 16" wheels instead of 15" that you currently have, you probably know this already.

 

Just go to Tire Rack, pick the brand you want and the specs will tell you everything you need to know. It shows the load weight for each rating as well as all pertinent dimensions including revs per mile.
