It's time for tires and I'm considering the above. The diameter is about the same (0.3" difference) and a 275 will fit on an 8.5" wheel. There seem to be more options at this size and prices are better too. Any reason not to? Experience? Thanks.

Two things with this that I think you need to be careful with. First is the fitment and how much distance you may have with the front spindle on the inside top of the tire. See below, the 285/35/22 on 10.5 22 ET35 existing setup is mine. I did a lot of research and measuring to ensure that that setup would fit on the front of the F-Pace. The SVR and the Standard F-Pace have the exact same fitment. As you can see from the setup you'll clear fine on that outside, but my concern would be on the inside top with the 275 section tire you will be very close to hitting the spindle on your stock 20 x 8.5 rims with the stock 45 offset. Note my setup when the tires are new only clears the spindle on the top inside by about 5mm. As you can see from the willtheyfit.com sizer it's looking like the 275 tread on those 45 offset wheels actually falls a little inside of my setup. So it's worth test fitting.

The other issue I think you need to consider is running a 275 tire on a rim that is only 8.5 wide. A couple of manufacturers recommend a minimum 9 inch wide rim for a 275, but some, like Continental say that you can put a 275 on a 8.5 rim as well. It's just a small width for a 275 tire.

I ran 285/45/20 Good Years on the Factory Wheels that are only 8.5". My tire guy verified the fitment and it looked great as it had a nice beefy overhang to make the tires look wider and stick out more as I feel the stock wheels with 255/50/20 tires look way too sucked in and give the F Pace a whimpy stance. I have since upgraded the wheels to 20x9 with 38 offset with the same 285/45/20 tires. Much more aggressive stance and zero issues with clearance. Performance is great as well.

Looks good. Thanks for the intel. If 285/45s fit then a 275/45 should give some cushion. I hadn't considered how close the top of the tire is to the spindle (it's close) until PA-FPace-F replied above. Good to hear there are no issues. All of the tire manufactures I've looked at say 8.5" wheels are safe for their 275/45 tires. Plus there are many more options at that size and they're less expense than 255/50s.

The 285/45/40s has very limited options for all season as I live in Michigan. There is a good 1/2" clearance on front struts. I originally went with 275's but the 275's didn't fill up or look much more "beefy" compared to the 255/50/20s. The 285/45/20s really made a difference in the "beefy" category as they are 1.2 inches wider than the 255/50/20s whereas the 275's were only 3/4" wider. Zero issues to date.

285's on factory 8.5" wheels are fine. Keep in mind that the information online is pretty conservative with tire widths on rims. If you talk to a very competent tire rep, they seem to know the true boundaries in order to maintain safety and performance.

It's surprising how much prices increase and options decrease for the 285s compared to the 275s...
