What size LT tires for 2010 Silverado 18" wheels ?

[Happy_Camper3]

Hello, I have 18" factory wheels, looking to replace my stock tires with LT tires.

Anyone ever get a size or two bigger ?

I have a 2" level kit, so I am told I can go a little bigger, how much I'm not sure ?

2010 silverado 1500 with factory 18" wheels,

What size tires ? Thank you!

On my '10-1500 4x4 I stepped up to a 275/6518 from the factory 265/65/18. Did not notice any change in driving with or without the trailer in tow (6500lbs, then our new to us ~7300lb trailer). Thing that was gone was the p rated tire "wiggle" due to sidewall flex.

I bought the Cooper A/T3's in LT C, and was very happy with them in all conditions. Never went kidding so can't comment on that though. Dry, wet, snow... a very good tire that I would buy again!

If you tow with that truck, I recommend staying stock sized. What is your OEM size?

Doesn't a change in tire size affect fuel mileage, odometer and speedometer accuracy?

What is your P meteic size? They will be the size you need.
