What is largest 18 in tires you can install with oem wheels? 275/55/18 or 255/60/18? Both of these have the same outside diameter and revs per mile as the stock tires.

i'm going 255/60's on my 18's when i need tires...imo that should be plenty for these vehicles...any larger vehicle won't be as good in the heavy snow...
I ordered up some Toyo Proxes STIII in a 255v/60/18 this is same revs per mile as original , so no speedo change: is very aggresive look. Will install on Colorado 18 in 8.5 wide rims. Will post pics as soon as Toyo Proxes ST III 255/60R18 112V XL Performance Tire | eBay

Colorado is not a Blazer?
Colorado wheel specs are the same as blazer. have different choice of 2015-2019 CHEVY COLORADO 18" FACTORY ORIGINAL OEM ALUMINUM WHEEL RIMS 5673 1116 | eBay
are the wheel wells the same?...are the Blazer 18's 8.5" wide?...i would prefer to see someones experience using the 255's on a Blazer with stock 18's
You can go to tire size.com/wheel-offset-calculator and plug in all of the specs for tires and wheel offset, width (use 1/2 the additional width as spacer spec) you then get a picture showing differences at top , inside suspension and out side fender well. You compare the original setup to proposed. really neat calculator .

looks like mud guards are needed with the 255's
Mud guards will keep the car cleaner, longer. I put mine on early on, from Amazon

No drill, easy installation.
