Looking at a couple 2013 f-150s that all have the 20 inch wheels on them. My biggest concern with the 20" tires was i heard that they were significantly more than 18" when it came time to replace them. I went online to price out some tires to see what the difference was and was surprised to see on tire rack that the 20" version of the michelin ltx m/s2 were $20 cheaper than the 18" per tire.although i was dissapointed they don't make an lt275 for the 20".
how much is it costing you guys to replace your 20" tires vs a set of 18"ers
Well, I had an F-150 with 20" tires. If you stick with the stock P-metric size, you're still cheap at only around 180 bux a tire. If you want to go up to an LT tire, then the prices are vastly more expensive than getting an LT for the 18" tire. The smallest LT tire on a 20" rim you can get will cost on the level of $300 a piece. But most people only need a P-metric style tire. I bought LT tires because I wanted something that had severe duty ratings for snow and ice... then I traded my truck and I'm back to all seasons. Oh well!
