Changing OEM tire size on 2017 CX9 Touring

V
2017 Mazda CX-9 Touring
So. I'm looking to replace the tires on my 2017 CX-9 Touring, but the OEM size is a huge pain to find as not many people seem to make the 255/60r18 tire. There's a few out there, but selection is really limited. So I'm toying with the notion of going up slightly to a 265. Lots more (and better) tires to choose from and only around .5" difference in diameter. I know about speedo/monitoring issues already and can live with that - but my main concern is how tight these guys tend to be in the wheel well. I've scanned the forum and Couldn't find anyone who has asked this question before, but has anyone here done this? I wanna pull the trigger on some nice Michelins that are a great price right now, but want some sort of confirmation before ordering them on tire rack and spending $700.

Thanks!

In this case, I don't think a 1/2" difference is going to make much of a difference. I had a 2008 Lexus IS250 AWD and replaced the stock 17x8 +45 offset wheels and 225/45/17 tires with 18x9.5 wheels and 245/40/18 tires, resulting in an 18.9mm difference in diameter. They did rub the wheel well liners on hard turns, but that was because I had lowered the car a few inches. But hold off and wait for someone more experienced than me to chime in.

I don't know if clearance will be an issue, however you also need to keep rim width in mind. I believe that the touring rims are 8" wide. I don't know if an 8" wide rim can take a 265 width tire.

Tirerack.com lists 8 tires in your size, and they don't stock all brands. They do list exactly ONE tire in 265/60-18.

Take a close look at the Pirelli Scorpion Verde all season or the Continental Crosscontact LX Sport. Either should do a fine job.
 
BF Goodrich

I had a set of BF Goodrich 265/60/R18 Advantage TA Sport tires installed on my 2017 CX-9 touring last month. So far, they have been great in the snow and there have been no issues with the slightly larger tire dimensions. I also ended up going this route due to the slim selection of tires in the OEM size. The original Yokohama tires were completely worn at 27,000 miles so I'm hoping that I have better luck with the BFG's.
