Are you referring to Aesthetics? Performance? According to the manufacturers, the 245/45 work on a 7.5" wheel. Admittedly they do not look as 'cool' as they are not lower profile and may not handle corners on a track as well, but better ride and more rubber on the road, so likely better stopping power.

I am referring to performance. Aesthetics isn't anywhere near as important, for me at least.

245 width tire on a 7.5" rim... oh dear. Sure it'll fit, but are you going to get the physical contact patch which a 245 width tire offers? absolutely not. Think of it is a balloon, the tire is not going to fit nice and tight onto the wheel. If you do a lot of highway driving and refrain from cornering your car in a spirited manner - ever, then it should be ok, otherwise I'd prefer a better fit onto the wheel. If you open the link I have provided and scroll down a little, you will find a useful chart. Based on my own first hand experience with tires and rims, I can confirm that this chart is perfectly accurate.

Too late now for me, hope it does not cause issues, but the tires are already on...... Was not much in the way of choices in 235 and I did not want to change out the wheels. Time will tell. I am pretty OCD about tire pressure, so I hope that will help......

245/40/19 would be alright because the diameter will be almost the same as 225/45/19, according to will they fit.com. but.... 245/45/19? On a 7.5" definetly not recommended. How does it feel? Can you take a picture of how they fit on the wheel?

Have not had a chance to drive them much yet as we are having a rare 3-4 day Rain event here in Phoenix. 3" so far...... But the little I did when it was dry and some in the rain, they felt better than the stock tires. Better ride, no mushy feel. Not too much quieter (per my decibel Meter). Here are a few pics, not great pics as it is dark and raining and did not open the garage. They look like tires looked before everyone went low profile. The 'balloon' in the pic does not look as dramatic in real life...........

Well, it doesnt look as bad as I initially thought but you can clearly tell the tires a little oversized.. if you went for a 40 sidewall the diameter would have at least been almost the same... you've altered the rolling diameter by about 2-3% which is a little much .

Discount and other threads said under 3% is OK.... Over is not. It is 2.6% so pushing the limits. But as the earlier poster said, the ride and feel seems better. It has a more premium ride and look, from the back at least!
If I change my mind or have issues, I will post and if I Love them, I will post!

Personally I'd get 18" aftermarket wheels and fit 245/45/18 tires on there, roughly .24 variation from OEM which is 225/55/17 on trims without the 19" wheels.

Like the look of 19"s but to be honest I think they're a bit too big for the car and I wouldnt be able to deal with the ride over Toronto roads here. At least my 55 sidewall is cushy lol.

With the turbo engine or even the NA 2.5 with an ecu tune, you will want the contact patch of 245 width tires.

In terms of traction, especially with all the torque of the turbo, a custom limited slip differential will sure go a long way. Requires extensive custom work however.

Only thing you need to do is put a little tire dressing on those and you're all set.

You done good. Everything about those tires is a huge improvement over the stock tires.

Curious what they set the tire pressure at.

The pressure is not on the receipt (the torque is at 110 which is 2 ft/lb more than the manual). I checked the next day and it seemed they were pretty close to the 35 lbs. I go up 1-1.5 on my digital gauge. Finally not raining today so I may get a chance to see how they do!

Try playing around with the tire pressures a little. I like to have my front tires at 37,38 or even 39 PSI to increase responsiveness and handling. Sometimes I set the pressures at all 4 corners the same, sometimes I just leave the rear tires at 2-3 psi less than the fronts @ 35.

are you at stock ride height? is there any rubbing?


i am just now ready to purchase tires. i wanted to let my stock tires "fall off" before purchasing new

I had the stock 17 and purchased stock 19s. My main concern will be comfort without really effecting fuel mileage too much since the wife drives it more than me

Ive read a few other posts of guys running 245/45 and they seem to love it. Much better ride.At this point i guess Im considering

245/45
235/45
245/40

ride comfort, fuel mileage at price are the 3 main considerations. i dont want the tire to stick outside of the fender wells because that just messes up the paint, but from ll the picture ive seen it doesnt look like this i an issues for any of these tires im not racing the car or trying to drift corners.


Im still considering opinion and suggestions

I have had the 245/45 Michelin on my M6 for a few months and a few thousand miles. Slightly better ride, still can break them loose from a standstill, mileage about the same (I account for the 2.6% bigger tire in the mileage calculation). I am happy with them, although I do not push the much in the corners anymore (that is why I got rid of my VW GTI to not be tempted).
All and all very satisfied......

I have a 2018 GRT 2.5. Any try the new Yokohama Advan Sport A/S+ yet. I too want a softer ride and good traction in Wet and Dry. I have snow tires on another set of Rims. So winter Traction is not important. Live in Wisconsin and need to deal with rough / Pot hole roads.
