Just had a question. What is the biggest tire size you can go on a 20" rim for a 4x4. I had 17: with the 265-75-17.I recently put 20s on mt truck with 275-55-20 tires. They look kinda small if you ask me wanted to know if anyone has any suggestions on going witha bigger size or just putting the old ones back on. I would like to maybe go to 65 series tire but they are hard to find below is a pic of the two with the old rims and new. let me know what you guys think Im also considering putting the old ones back on. reason for this is the new rims ride kinda ruff . So wanted to know maybe if i put a bigger size tire it will help.

 

i've seen a few Rams with I think 305/55/20 on them...

I think that's what they were.. looked amazing...

 

I'm not sure what the metric measurement is but whatever would come out to a 33x12.5x20 tire

 

i just ordered some 305 50 20's ill post pics when i get them in. i went lower on the aspect ration because i wanted to help offset for the heavier tire and maybe preserve some fuel mileage.

 

Is urs a 4x4 TT.?? what rims do u like better.

 

Are there any rubbing concerns with he 305's?

 

I'm running 305/50/20s and love 'em. ZERO rubbing.

 

i like the new ones!

 

i'm running 295/45/20...my next tire is gonna be a 305/40/20....bigger the better

 

hey John M . Did you notice a difference in the ride?any way you can post some pis of the truck.
