Alright I'm looking at my options for new tires for my truck. My project is making a camper truck, that's still very off road capable. I want to take it up through Canada and Alaska, so it'll see alot of highway miles.
I'm exploring the possibility of running commercial truck wheels (10 lug 22.5x8.25), and commercial tires.
I'll get good ground clearance from the height of the tires. (tires listed below are 41-44" tall)
I'll get great fuel economy for a tire that big.
They should be easily available just about anywhere.
They should last over 300K miles.
Each tire is rated to 6175lbs (The truck's 6280lbs now , I expect almost 9K after the camper is loaded)
The large diameter rims, and narrow tires with stiff sidewalls, should help in the snow.
I went to a local dealer and they recomended some Kelly KDM drive tires front and rear.
They are $392 per tire (I could get cheaper retreads in the rear too), wheels would be $95 for steel, or $250 for aluminum.
Here are the specs for the tire.
Also, take a look at this website, www.ricksontruck.com, they carry 19.5" tires for the same kind of application.
Thought I'd post some of the figures I was coming across,
225/75/R16 stock tires = 37lbs each, 148lbs total
My 38/15.50/R18 tires = 98lbs each, 392lbs total
KDM 295/75/R22.5 tires = 128lbs each, 512lbs total
16X6.5 stock wheels = 26lbs each, 104lbs total
My 18X12.50 wheels = 36lbs each, 144lbs total
22.5X8.25 wheels = 55lbs each, 220lbs total
480lb difference from stock to commercial tires
196lb difference from my current setup to commercial tires
It's definitely some additional weight, I'm wondering if it will be worth it.
Right now the motor is making around 400HP/700TQ to the wheels. I don't think it'll have a problem with the weight of the tires.
So what are your thoughts?
