:eek: i have 275 -60-15 tires on my truck and it really slow and it burns alot of gas ,and recently i had to rebuild my transmision . and i dont even push my truck,could my tires be responsible for the problems , they are very wide,and lower than 235 's .im tring to make up my mind on getting 235's .could anybody help.thank you

275/60/15 = 28x10.8
235/75/15 = 29x9.25

Very slight difference. That won't affect the tranny at all, and would only slightly affect mileage.

If you like the look of the 275s, I would just stick with them. They aren't hurtin ya.

i really like my tires , the looks good ,with them . so then it must be the myth about changing transmision oil , i got my oil changed and i notice my truck was getting into gear hard. maybe the change of oil did it
