I wanted to go with a 295 back and 265 front with 18" bullits but was told I would need a tune for those sizes. What would be the biggest size recommended to get without having to get a tune. I wanted Vredesteins but was told those are wider than the average tire.

 

you dont need a tuner if you stay at the same height tire as stock even so its a very very mild difference in the speedo dont worry about it
