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!

Do you need a ladder to get down off that high horse?

I found the forum know-it-all within 24hrs of joining. That must be a record.

Also, who is we? You are the only person in this thread being pretentious. Every other comment was both helpful and respectful.

yup lol. doesn't even have a cx5 but knows everything about them lol even tho i think he only had a rental once lol...

I wanted to apologize for my last post. I realized I was disregarding your preference for aesthetics just because it differs from my own focus on handling mechanics. My 'beyond me' comment was uncalled for, as we all enjoy our cars in different ways.

The wheels on my wife’s Mazda6 are 7.5"
Hmmm…
I wonder if she would notice

It's all good. I appreciate you saying that.

That said, it makes more sense to get new wheels and tires vs new tires for the stock wheels and then new wheels and tires again later (i'd want wider than 245 with a wider wheel).

I have 9" wheels and went with 245/45/20 +45 for my setup. I kept everything exactly the same as Mazda's standard sizing. But I could see preferring 255/45/20 for a little meatier look and a little bit softer ride quality if one didn't care about sacrificing a little bit of sportiness. It wouldn't be a night and day difference but it might be noticeable.

@N7turbo how's your fender clearance with the 9" wheel? I know you said there's still space near the strut.

Sorry, coming late to this party...

Yea, that's assuming you actually get the extra 10mm contact patch. You won't.

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 don't agree, actually. A wider tire will have a wider contact patch. The tread area is significantly thicker and stiffer than the sidewall, so the sidewalls will be forced to angle in to the wheel, leaving the tread (at least mostly) the same width as with a wider rim. The danger is that (as others mentioned) you might have a bad bead interface if you go too wide. See example pic below.

I see. Thanks for sharing. So, if simply a wider tire contact patch is the goal, you can do it, (within manf. approved wheel width range) but sidewall stiffness will be compromised somewhat, although, I don't think that would be an issue unless you enjoy to corner in a spirited manner.

@AfCtAJHR26 I switched to some flow-formed wheels (17x7.5 OEM to 17x8) and saved nearly 10lb per corner. It made a noticeable difference.

But, if you're not worried about weight savings and like your OEM wheels, in theory, you can go wider without problem.
