Ok Accord fam! I bought a set of Konig Countergrams for my civic which since been traded in for my lovely Accord 2.0t sport 6mt. Now the question is they're 18x8.5 which I prefer to the 19's anyways...what's the biggest tire you can run on that size rim? I'm hoping for a 255/45/18 I just want some more sidewall to absorb our crap roads. I will be lowering with the H&R OE spring because I don't want a slammed car in the winter or in my construction zone neighbourhood!

It will be 27 inches tall compared to 26.4 stock. The width should be fine as long as you don’t have some crazy offset. It will be taller though.

235/45R18, 245/45R18, or 255/40R18 would be preferable over the 255/45R18, especially if you're planning to lower on lowering springs. 255/45 being taller than OEM, it would give you more ground clearance, but you may run into an issue with the tire tucking into the fenders more than wanted.

Going down to 18s, you don't want to get a really big sidewalled bulky tire because it will make the 18s appear even smaller and won't look good. My personal recommendation would be the 235/45 or 255/40.

Are the Countergrams +35 offset or +43?

This is what I'm looking for!! They are +35 I just didn't want the gap to look massive until I lower it a bit I am leaning towards the 255/40 to give it some meat. I may run spacers after the test fit to see if I can push it out

OEM is 19x8.5 +50 so you're already pushing them out 15mm with the 18x8.5+35 wheels. The OEM tires are 9.25" wide and the 255/40 will be 10", so you're getting wider tires as well (about 10mm further out). Giving you a setup that's 25mm closer to the fender. I don't think you'll need to get spacers at all ;)

I have 255 40 18s. If I had to do it over, I'd get 255 45 or 245 45. (offset is 45mm)
