Anyone know tire size VS rear end ratio

[DZLROKET]

IE: I have 265/17" on my 2500 06 4X4 w/ 4. 10 rear



its a little too low geared for my use (I don't tow much) and my fuel milege is not that great. What tire size would bring my ratio back to

3. 73 ??

I believe you'll have to increase tire size to "35's". That'll help lower your rpm's but the added weight and drag of the bigger tires may negate the gains.

Thanks, so what is the diameter of my 265/75/17's?

The 4. 10-35 combo is nice it will give you about 2k @ 70mph still good for most towing.

265 are usualy around 32 inches tall. every inch of tire you add is about 7 gear points. So 410's will be (roughly)403's if you add 1 inch of tire.
