235 vs 225

[SnowDrift]

I put skinny tires (225/60R16) on my polished pre-gen wheels for the winter since the belts were showing on my other tires. They're Cobra 5 spokes and I have 235/55R17 on them. The tread width and tire carcass is about 1-1/4" wider on the 235 than the 225. I guess the reason I'm bringing it up is for winter consideration. If someone is debating on width for tires that will see snow, consider that 10mm should equal less than 1/2" in width, but it's obvious in this case that it's not necessarily true. Perhaps the "235" is some sort of nominal dimension and not a physical measurement?

Cooper Mastercraft Avenger Touring LSR in both cases. Made in USA tires. 235s are 50,000 mile tires and the 225s are 80,000 mile tires, for reference.

the 225 or 235 is mm across the tire. so your right 10 mm wider, wont make a difference at all in snow.

that trick is for trucks with like 35' to 44's on them or tall retarded wide tires. a stock tire size does better in snow vs the huge over sized tires as all the trucks weight is on a much smaller footprint.

" The tread width and tire carcass is about 1-1/4" wider on the 235 than the 225."

Might help a little. The point I was making was that the new 225s I put on are about 1-1/4" narrower than the 235s they replaced, not 10mm that I thought they would be. I'd have never thought this would be the case because the dimension is supposed to be a physical dimension. I cannot explain.

tire brand vary size from one to another, even specific models within one company do. you'll never have the same size tires unless you're comparing specific brand AND model tire to each other. those measurements aren't 100% law.
