Max tire width for factory 19x7?

[AfCtAJHR26]

My biggest gripe with the aesthetics of our '22 CX-5 Turbo is how skinny the factory 225/55r19 setup looks. Blows my mind why Mazda would go with a 7inch wheel for the premium option on this car. It really gives the car that "skipped leg day" look. Our 12 year old Tiguan R-Line came with 19x9s from the factory.

Has anyone tried squeezing a 235 or 245 on the stock 19x7s?

I do plan to get aftermarket wheels eventually, but in the short term, some wider tires and spacers would be an enormous improvement.

Thanks in advance for your comments and advice!

a 235 should be no issue it would be about a .2"poke and .2" further inside so should not be an issue. 235/55-19 are good for wheels 6.5-8.5 wide..
245's are good for 7-8.5 wheels so a 245/50-19 should be about the same height and .35" poke and .35" closer inside.

Thanks for the reply!

When you do a general search online, a lot of people say that a 245 on a 7inch wheel is pushing it and will "bulge". But the tires I have looked at have an approved range of 7"-8.5".

Depends on the approved width aaccording to the tire you're looking to put on.

Let me tell you, Mazda's engineers focused on the optimal contact patch for handling and fuel economy, not aesthetics.

I have a similar 225/55R17 OEM size for my Mazda 6. I am currently running 235/50R17. Unless you like to regular cornering at or near the limit of grip, you don't need wider tires. I like the extra grip, but 225 did give the car slightly more playful rotation when cornering hard.

If you must have wider tires for whatever reason, go for it, just stay within the range specified for the tire you're looking into, and be sure to also consider what contact patch the manufacturer actually specifies. You'll want an 8" or 8.5" wheel for 235 245 if you're concerned about a tight sidewall fit for good cornering performance.

I'm also interested in a larger tire for my 25 CX-CX-55 (PP with the 19×7 wheels). I think that the fender gap is too wide and the ride could be softer. So, a 235/55 is in my near future. I'm anticipating using forscan to re-calibrate the speedometer for a larger diameter tire. We'll see. I agree that a 7-inch wheel width was not a good design on Mazda's part.

Part of the reason they may not look much wider is because without a wider wheel supporting them, they will look rounder. Think dragster instead of steamroller.

I was told this isn't possible and that not even Mazda dealerships can do it. I would like to believe there is a way.
