What would the the next size tires up from a 245 75 16 I have a 2002 x cab 4x4 off road , and just want to go a little bigger, one size up, I do a lot of highway driving and want to drop rpms a little, I have 4 10 s so not worried about losing a little bit of gearing,thank you

 

Do you want wider and taller, or just taller. If both, a 265 75 16 Is roughly a 31x10.5x16

 

Will that kill the 4-10s I was thinking 255 70 16, what do you think, they are30.5 inches tall and a little over 10 inches wide, they would not rub would they

 

I would say they are closer to 32s. I think the conversion is 31.6 or 31.7. Obviously all manufacturers will differ a little bit.

32s will not kill your 4.10s. I ran 265/75r16 on my truck for 5 years with 3.55s. Stock FX4 rangers come with 31x10.5x16 tires and 4.10 gears. If you go with the 265/75r16 you will only be increasing tire size a little bit. Your highway MPG will increase slightly and your city MPG will decrease slightly.

The tires you mentioned will not rub. 265/75r16 is as big as you can go without rubbing. You may have to trim just a little bit, but it will only rub under extreme flexing.

 

I had a 4.10 with these 265-75-16s for a few years. No problem at all. Still plenty of get up and go with a 3.0. I just regeared to a 4.88 to allow for 35s in the very near future. You have nothing to worry about.

 

I have fender flares and mud flaps, the won't rub under daily driving?

 

No, it won't rub. I'm running 33's with 4.10's btw. It's slow but it does just fine.

 

I too have fender flares and mud flaps. You have nothing to worry about. Just buy them
