Whats the tire size on an RST? Is it 275/55/20 or is it a little smaller?

 

275/45/20. At least that is what is on mine. I would like to go with a bit taller tire when I get around to it.

 

According to the truck trend article about the silverado rst.....it came with 265 50 20. However, when I got mine it had 275 45 20 and they were original tires.

 

Another 275/45/20 here. I just bought some 275/40's I'm switching to. Hope to be on a 4/6 or lower drop real soon!

 

I thought they looked little smaller than my tires. I know the articles for Joe Gibbs trucks shows 275/55 as the stock size but I wanted to look into it a bit since my speedo is off. My friend was following me the other day and told me I was driving so fast, then we checked and its off by about 4mph (says Im going slower than i actually am). No biggie, just curious what RST guys were running.

 

i ran 275/55/20 on my rst for a short while, and it ate up the inner fender covers from rubbing. im now back to my stock size of 275/45/20, with no rub.

 

I notice you have added sway bars and Hurst short throw shifter. I have an 06 RST and wondering how those modifications worked out for you. Can you tell any differences from the original? I'm also thinking some type of programmer or chip if they make a noticable difference.

My RST also came with 275x45x20. Just changed out Eagle GT II for Michelin Lattitued Tour. Wow, what a difference in every catagory, especially the ride, noise and rear end shake. I'll be working toward some rear shocks next to prevent bouncing.

Thanks,

My 06, White/orange RST came stock with Goodyear Eagle GT II, 275x45x20. I just upgraded to Michelin Lattitude Tour of the same size. Made a huge difference in ride, noise the rear end shake. I liked the truck before, now I love it.
