Anybody running LT305/65R18 with leveling kit?

[Ramin258]

I have a 2011 GMC 3500HD 4x4 SRW, 6.0 gas with 4.10 gears. I would like to put on BFG All Terrains LT305/65R18 with a torsion bar level kit from Suspension Maxx. Does anyone have a similar setup? I am curious if my mileage is going to suffer to much. Also concerned with towing, I tow a 7000 lb 5th wheel. Would this tire size effect towing much? I think this size tire will look great on the truck but if performance suffers too much I will just go with BFG LT275/70R18. Any input would be appreciated.

I'm running 305/40ZR22's with no level and no rub, that part should be okay. As for the towing and gearing, I have the six speed with 3.73's and first gear is still very short and I'm still rated at over 10,000 towing capacity. My only worry for you would be snow. The wide tires tend to float around on top of the snow, while something narrower tends to have a little better bite. Of course you may be in Florida...

Dinofishon,

 

Did the leveling kit change your ride much? Do the tires hurt your mpg too bad?

No, and No
