It depends on the tire because some run narrower and some run wider. In general, I wouldn’t go wider than 265 on the front (9” wide wheel) and wouldn’t go wider than 285 on the rear (9.5” wide wheel). I’m sure others have gone wider but I wouldn’t. Tire Rack has good info on their site with each specific tire showing recommended wheel width ranges. The Ford setup of 255 front and 275 rear is a good setup IMO.

Pretty much EVERY tire manufacturer has this for every tire they make. And most of the big retailers have this info on their sites too. Yet the how big of a tire can I fit on a given wheel question gets asked all the time for some reason. I guess because a bunch on yoo-hoos on the internet know more than the people who make the tires.

Now the how big of a tire can I fit on a specific car is a more complicated question, and one that every manufacturer DOESN'T cover.

A lot of times it becomes more of a question of how big SHOULD you go vs how big CAN you go. Just because you can, doesn’t mean you should in a lot of cases. Some have a harder time grasping that concept than others.

Some will say they haven’t had issues with a tire that is too big for the wheel, so that justifies their decision even though they could have a problem at any time that could be catastrophic. I’m sure we’ve all seen our fair share of nasty accidents due to poor wheels/tires decisions . It doesn’t end well, particularly at higher speeds.

Not to mention this horse has been beat to death a thousand times over on this forum…

It is somewhat tire dependent but if you just want to have widest tire possible (and the most grip) then I've ran 285s all around but the tire shop said that they would prefer to not try to squeeze 285 on a 9" wide wheel again.

You don't need to do any hand waiving, look up the tire you want and see what the minimum required rim is.

I'm running DWS06's 265 up front and 285 in the back, that's the maximum allowed width for that tire on the PP1 rims.

But here's the thing, you need to consider the aspect ratio, I was so wrapped up in getting the "widest tires possible" that I selected an aspect ratio that was "close enough". I did 285/35/19 in the rear and 265/35/19 up front. The tires I wanted didn't come in the 40 aspect ratio in the width I wanted. The result was that they don't fill the space as well and the fitment looks wonky. I'm stuck with that until I wear them out. I would gladly trade that small amount of tread width for more sidewall and a better look. The extra cm is doing basically zero for my traction.


Look at the actual tread width (this is also in the manufacturer's data for the tire) You'll find that its not a big difference between the two overall width options. On some of the tires I looked at there was no difference at all between a stock sized tire and a "maxed out " tire.

DWS06+ shown below for an example:

Only .3" difference here, its not really worth it.

I was in a shop one time getting a nail out of a tire and saw one of the associates refuse to put a tire that was too narrow for the wheel (was a kid that wanted the stretch look). Tire associate said it was a safety issue and didn’t want the liability if something happened since the wheel size was not within the tire manufacturer recommended range. Kid walked out and went to find someone that would do it for him.

This wasn't that extreme stretched look, it actually looked reasonable and had some merit with tire having very stiff sidewall (which made it also difficult to mount) - it was Bridgestone RE-71R and that width did provide some benefit - but for shop it was a struggle.

Also, to be exact - it wasn't exactly the PP1 rims but a set of aftermarket ones with same exact widths.

All tire models/sizes are not created equal! A 265 or 275 from one brand or model is not necessarily the same as another. What I follow is Tread Width, not Section Width. Tread Width is a figure that Tire Rack publishes for all models and size tire.

Assuming you have a 9.5" wheel, I would target a Tread Width of 9"-9.5" but no wider for a properly fitting tire. If you go wider, it may physically fit and stay on the rim, but the negative characteristics will likely outweigh any benefits to a wider contact patch. You want your tire to fit properly.

Yeah, I was just mentioning an experience I saw in a shop one time. So some shops will refuse to put tires on wheels that don’t fit in the recommended manufacturer range. Seems like they’re afraid of potential liability

Billy Johnson wrote a great article for MotoIQ a few years back talking about proper wheel and tire fitment. It’s been linked several times in this forum so I won’t link it again, but Google is your friend. Great article and worth reading, especially for those newer to the wheel/tire fitment part of the hobby.

Yessir! I now use that when making any tire size decisions.

I see mostly track tire fitment advice given on this board. If you can live with a bit of sidewall bulge you can fit wider tires.
