    I have 265/65/18's on my truck, but i have a set of 17" steel rims for winter from the same year truck. GM puts both 265/70/17 and 245/70/17 on these rims.
    Im thinking about putting 235/80/17's on for winter
    17"x7.5" rims
    Will this work or is it too narrow a tire?
    7.5" rim vs aprox 9.25" tire
    thanks

    Never mind,
    should have read further, tire is recommended for use on 6-7.5" rim widths

    The 235 80s will rock in the snow, especially if you get real snow tires and run some weight

    Im up in the air, i ran 265/70/17 Winters last year (winterforce UV) They were alright i guess wore quickly but thats probably because it snow'd less that 12" last year, lots of dry and wet pavement driving, but i never noticed a huge difference running a dedicated snow, i always ran AT's or MT's. 8 months since i last used my Transforce AT's.
    Maybe it is because i adjust accordingly and was used to driving military trucks with the solid hockey puck tread design in the winter.
    In any event im trying to decide between a transforce AT (or similar) again or LT winterforce in either the stock 265/70/17, 245/75/17, or the skinny's 235/80/17

    Thought I recall from past tire/wheel research that ideally the rim width should be between 60-80% of the tire width.

    a 235 will outperform a 245 or 265 in the snow.

    Just bought General Grabbers AT2 235/85/16 for my 2006 GMC 2500 HD reg cab 8'box. I am running an extream V 7 1/2. I can't wait to try them. Last year I had 265/75/16 and the truck would perform well. Everything I read on plowsites skinny and tall is the way to go.

    Studs? What do you run for ballast? Why did you put such a small plow on the truck?

    I bought the truck & plow as a package. I run ~1100 lbs for ballast. And I am running studs

    Im curious to see how you like them. I ran a studded set 235/85 on my 97K2500 with an 8-6 XV. Always ran the truck very heavy. Could not plow 4 inches of powder off a flat lot in 2wd.

    But most people praise their performance. So let us know how you like them.
