I know Champ said 235/35zr19 and 265/35zr19 tires will suffice for track. I was wondering if this is the same for everyday use as well.

I'd run a 40 series up front to keep the OD the same front to rear, like in a stock setup. I wouldn't stagger wheel diameters. IOW, 235/40/19 and 265/35/19.

I'm thinking of running those sizes when my tires wear out. The problem is, there a slim pickings as far as selection is concerned. I may put a 245/35/19 up front instead, but that's about .3" to short.

Ah, decisions:mad:

I'm thinking of putting the Michelin® Pilot® Sport A/S Plus 235/35ZR19 for the front and 275/35ZR19 for the rear. I'm a little worried about the clearance and if there would be a significant enough change in the speedo. There's also the 245/40ZR19 on the front as well. The rear size is really my concern I'm worried about rubbing as well.

235/35/19 is too short and 245/40/19 is too tall. 275/35/19 is also too tall, and as you said I'd be worrying about potential rub. However, from where I now sit, I believe I'll replace with PS2s in the 245/35/19 in front and 265/35/19 in back.

Can you please send us pics of this once it's done? Thanks.

I'd probably just stick with the OE sizes, but that's just me!

The problem with the OE tires is there 10k mile tires and for Summer. Which is fine if you live in an area where the climate doesn't drop below 40. Once you get down under 40 you will see significant tread wear. I dunno about the rest of you guys but I don't really feel like spending $1500-$2000 on tires every 6 to 8 months.

I agree, but it's hard to find all-weather tires for the sizes we have. If someone knows where we could get OE all-weather tires with longer tread wear, please inform.

Ok, we buy a car like this for it's performance and handling - Right:confused:
I know that's why I did:eek: It's an awesome car:p Why in the world would you want to dumb it down with an All-Weather Tire:confused:

If you wanted a car that had long tire wear, you should not have looked at the F, or any other high performance vehicle for that matter.

The F, and all other speciality high performance cars, and tested with a particular brand and model of tire during design and testing. These tires are fitted to the final production models. In the Fs case, Michelin PS2s and Bridgestone RE050s. In other words, the car and the tire are a system made to work with each to get the most out of the handling of the vehicle it was designed for.

However, there is a choice is you wanted to do this, again beyond me. But, you would need to go with 18" wheels. There are some that will fit the F. The only all-weather tire I could find is:

Good Luck to you in your endeavor.

Oh, as a PS. - As far as cost is concerned. We paid a lot of money up front for this car, now we need to feed it with the proper amount of cash necessary to maintain it to it's fullest potential, or modify it to make it even better:D

I don't disagree with you Lou but in the area I live we have a problem with this stuff called snow. From time to time and since this is my primary car I don't have the option for a non AS tire.

I'll soon have a mortgage payment that will eat both my pay checks so I can't afford to spend $1500-$2000 on tires ever year. I'll have the best of both worlds being able to drive my F all year round.

I don't see why going to Michelin Pilot Sport A/S Plus is a drastic downgrade. Your making it seem like I want to put some no name brand tire on the F which isn't the case. I understand the OEM tires were made for the car but for me there just not practical and that's why I need to look at something with a longer tread life.

I'll be going with Michelin® Pilot® Sport A/S Plus

Front - 245/40ZR19
Rear - 275/35ZR19

Here are the specs for the Michelin® Pilot® Sport A/S Plus:

I went with a snow tire package for my F, which I guess should end up extending the wear on my summer tires. We don't get tons of snow here, but my previous experience with rwd and a/s tires in my 93 525i was less than successful. I got stuck in a parking spot once :mad:

Hopefully with traction and stability control, you will get along okay with the all season tires.

Good luck!

The Michelin Pilot Sport A/S Plus are made for light snow. After an inch or two you'll have a hard time getting around in the F anyway since it's only a few inches off the ground. We don't get much snow here but when we do it's usually pretty bad. The problem like I said a few posts ago it's the temp in the area. All winter it's 40 degrees and lower which kills the OEM tires. The tons of salt DOT throws on the road doesn't help. I'd go with winter tires but then I'd have to worry about two sets of tires at that point which isn't worth it for me. The last time I looked at winter tires the Lexus dealership quoted me $1400 for winter tires and I just laughed.

I will also need a snow tire package as well. Living in Toronto we get TONS of snow, so hopefully with the summer/winter tire packages I'll sort of 'save' money and tread, but probably it evens out, who knows.

That's a part of the reason why I'd stick with OE sizes, but to each their own. :)

When I went to the dealership they tried to set me up with Bridgestone Blizzak LM-25. They fit on the OEM rims and should be way way better then the OEM tires.

I wouldn't want to use my OEM rims as winter rims, unless I purchase a set of summer rims that would be more expensive than the OEMs, so probably I'd just buy a set of relatively 'garbage' rims that look decent and slap the winters on that. I was thinking the exact same tire though, the Blizzak LM-25s, but I'm tempted to get them in a size smaller, in 18s, so that there's more bite in the winter with a thinner contact patch as well.

I got a set of MSW rims ($126/ea) and LM-25s in 225/45/18 all around. It has worked pretty well so far, it certainly does as well or slightly better than my 04 TL with all season tires. The ride is slightly better too with the bigger sidewalls. I'm sure handling is a lot worse, but I don't really want to push it with the snow tires anyway :)

Thanks for all the input. Apparently there's a lot of choices out there besides the summer tires, and it doesn't hurt to chose a more practical one for your ride.

Would 255s in the rear be better? Or just go 225 all around for better bite in the rear tires? Just that with 225s in the back, the car would look kinda weird. But I guess functionality over looks, haha.

Usually narrower tires do better in the snow, AFAIK. This is the package that was recommended for the IS-F.

I suppose it would look better with the wider tires, but I decided to go with the recommended package for maximum winter performance.

Good luck,
