Towing tire confusion
Hello. New to the community and I am hoping someone can clear up some confusion on tires. I recently purchased a 2024 chevrolet 2500 hd custom with 20" wheels w/ 275/65/17 tires. In the towing section it says my current setup is rated at 12k for a bumper pull trailer. (I have a 16k equipment trailer, long story) However, if I switch to stock 17 inch wheels w/ 245/75 17. I can get 14.5k. If I go stock 18 inch w/ 275/70/18 mt tires, I can get 16k. And if i had the zr2 package, I would have 305/70/18 mt tires (bigger than what i have now) and able to tow 16k. heres my dilemma: I want to get more towing capacity when I need it in a second set of wheels and tires. I understand that more sidewall helps (smaller wheel) and a less overall diameter helps (smaller tire). Here's the question: I have a set of stock 17 inch wheels from a 2018 silverado hd. I've found a 295/70/17 BFG tire with a similar load index (125 vs 126 that I have). It has more side wall than I have now (over an inch) and smaller diameter but not enough to throw the speedo way out. (About 1.5 mph at 60mph). Would this combo get me at least to the 14.5k? Or is this wishful thinking. The wheels were new take offs in really nice shape so, I'd like to use them if I can. Thanks!1.5KViews0likes15Comments
