I should be getting tires for my H2 wheels next week and want to get some smaller tires to use at the track for my stock wheels.

It's a 2500HD and currently has 33's on it. I'd probably swap the tires at home, so I'll need something suitable for an hour ride on the highway as well.

 

what gear ratio? maybe something around 31"

 

It has 4.10's. So, just go with the stock size? I think they were 245/70's but I can't remember, I'll have to check the door placard...

 

I use like a 265 70 or 75
