Hi everyone,

I will be taking delivery of my X premium in the beginning of Jan. First thing that I would like to do is to swap the Goodyear tire with Michelin (nothing against the Goodyear btw). I talked to the local tire dealer who is willing to accept the trade in, he told me that 245/65R17 should fit X’s rim.

As most of you are aware that the X is fitted with 235/65R17, do you think if there are any advantage going with the slightly wider tire? Pro and Cons? Will this tire fit? Other high performance tire I should consider?

Thank you in advance

I would love to know that as well. :2:
The X would look more aggressive with beefier tires.

The biggest thing against wider treads is losing traction ability in the wet and snow. Interesting the comments should come from the east coast. :4:

Also, 'grippier' wider treads for warm seasons usually means more rolling resistance and mileage will suffer maybe a fraction of an mpg.
Everything is a tradeoff. While not the offroad 'king', the MDX has done splendily
on snow and ice in various road tests.
Reducing the propensity for hydroplaning is a real advantage especially in an SUV, IMHO.

Specs

Go to this site to check out the specs for whatever tire you are considering.

With the 245 you not changing it much. The speedo error is 1.8%. When your speedometer reads 60 your actually going 61.1.

WIDER TIRES

That's one thing that really pissed me off about the MDX. The wheel size is 6.5". It wouldn't have killed them to put a 7" rim on there. The tires would fit just as well. In fact 235 IS THE LARGEST tire that should safely fit a 6.5" rim.

In order to avoid spedometer error your choice of upsizing are 255/60 or 275/55, both which have the same total height as 235/65. These are in fact offered in Michelins excellent Cross Terrain that's stock in touring models. Of course for safety you shoud get at least a 7" rim although I know plenty of shops that would "squeeze" the 255 on.

Of note, if you want to see what a 275/55 looks like, just check out the next Mercedes ML you see. This is the size on their sport models. IMO it looks pretty cool, but then again w'ere not driving a mercedes, are we. I think you gas mileage and your snow traction (if that applies to you) would suffer. I think the 255/60 is a good compromise between improved handling , looks and wet weather traction. Again, maybe you could find a shop that would put them on the stock rim. Good luck, I hope this helps.

245.....???

You'd go through the expense to swap out a mfg recommended tire size to gain 3/8 of an inch?!

I could see a swap that adds 20 or 30mm or more... but as others have pointed out you'll need new rims.. then questions of clearance/fit (on the front) enter the equation.

Keep in mind that if you find a shop that claims the 6.5inch is OK, they are incompetent. Tires become less stable as the tread width increases past the safe limit for a given rim width.
