I put my rims and tires on 2 1/2 weeks ago. I bought 2 brand new kumho's and i had 2 left from last year that were still in good condition. Now i have a bubble in all 4 tires! Last year i had 2 bubbles the whole time i had the rims on my car. I run 40's and now that i need to get them changed i want to either go 45 or 50. What do you guys think? would 50's work with my setup? thanks in advance

 

You must have hit a major speed bump or pothole

 

This is what i don't understand. I have been real careful but they just keep popping up. I know on one of them i hit a big pothole and got a bubble, but the other 3 i have no idea

 

Go with 45's.

 

Do you think that will be enough? Im not tryin to replace tires every 2 weeks
