On a road trip, LR tire 265-70-16 got a big bubble. Pulled into Indy tire shop, the guy installed used 265-75-16. We drive another 200 miles, never noticing anything. No pull, no nothing. Look at new used tire the next morning, notice it’s a 75 instead of a 70. YES I know this is not optimal. Question is, it is a small difference not causing any apparent difference or problem, so can I continue? Is it negligible? Vehicle is 2004 Chevy Avalanche. 275K miles. Thanks for any advice.
