If you read my other thread you know I need 4 new tires. I have read a bunch on tires and determined that I would rather not have RFT. Here is what i am getting from tirerack.com:

225/40ZR18 XL Michelin Pilot Sport PS2
Blackwall

255/35ZR18 XL Michelin Pilot Sport PS2
Blackwall

Having them shipped to BMW for install. Looks right to me but I don't know what I am doing. Thanks.

FYI I live in Vegas so the fact these are summer tires is not a problem.

This is a post that belongs in the tire section (towed). Also you forgot to mention what car this is for, your contact information says your car is an Accord, but I think this is for an e9x.

Also what are you asking for? Opinion on the tires (PS2) or on the size? What do you have on the car right now?

Sorry.

2007 335i. Need opinion on the size, and if there is a reasonably cheaper alternative. I currently have the OEM RFT on the car, and all four tires need to be replaced. The dealer is offering to replace all 4 tires for $1100 plus tax.

I don't know, my car is at the dealership. I assume whatever the oem is for the 335i with sport package.

Sports package should come with the same sizes you quoted above, unless you have the optional 19" wheels. At the very least, call your dealership and verify what size wheels you have on your cars. You don't want to buy/ship 18" tires if you have 19 or 17" wheels.

The PS2 are great tires, but they are not known for excellent tread wear, i.e. they will not last you very long. Maybe 15-20k miles for the rears if you drive normally. Less if you are hard on the throttle, more if you drive like a grandpa, a very very conservative grandpa that is.

If you are not looking for best performance out of the tires and you do not drive the car hard around corners, etc, then maybe going with an all season alternative is better. It will be a cheaper tire and will last longer. Check out Continental all seasons for example.

Also it is not a must to go with the staggered setup (wider tires in the rear) if you do not drive hard. Going with 225/40/18 on all corners will be a bit cheaper.

Mrykan - i know that this post was towed but i just read the that you recommended that non staggered is ok... am planning on getting that on my e90. And was worried that the "non staggered" might look dumpy.

Non "staggered" tires will look the same from the side (sidewall height is determined by "aspect ratio" X tread width...so 225X45 is approx same as 255X40...)...
What you do need to be carefull of if you switch to all one size tire..the smaller width/higher aspect ratio to save a few bucks...is that the tire you pick is designed to fit the wider rear rims....BMW puts 1/2" wider (8 1/2 vs 8) on the staggered wheel set...so you need to look on Tire Rack's "Spec Page" for the tires you are considering....you will see "allowable rim width"...just make sure the width of the rear rims falls in this range...I've found that not all 225/45X17 tires will fit on my rear rims...

Take for example the Conti Extreme Contact DWS...ultra hi perf all season tires with great tread wear rating(540)....the 225/45 size will not fit on 8 1/2 inch rims....but the larger 255/40 size tires are only $8 more than the smaller ones, so why not stick with staggered sizing?...BMW says "no tire rotation reccomended, even for cars with all same sized tires"....so rotation isn't a reason to go all one size..only $$ savings...

Also something to consider is that if the car came with a staggered setup from the factory, not only are the width of the rear rims wider, but the offset is different too. The offset as well as the width of the wheel and tire are set up so that the rears will have a more aggressive look and pretty much stick out the same as the fronts, so if you put a more narrow tire on the rear wheel, it may appear that the rear tires are sitting in under the wheel wells slightly. Not to mention some of the performance and handling aspects associated with a tire that is a 255 width vs a 225 width.

Just my opinion

Samger2 and SpitPilot - thank you for your comments. I have gone back and forth with Nick @ JSlev..I am thinking of getting VMR VB3 - and having same size on all corners should be ok. Plus I have an XI and have very limited options on the type of wheels i can get.

The correct way to do it would be to go with the current size, with the correct speed rating. Particular to the options on the car, there is a recommended speed rating. I would recommend focusing on that. Your location works in your favor. Most likely the speed rating is a high 90's V rating, which means they are High Performance all season tires. Z, W, and Y ratings will work just fine for you. keeping in mind those will tend to wear more quickly but give you better performance. I would highly recommend the Continetal Extreme Contact DWS. That tire is great on performance, ride quality, and life expectancy. The tread wear is @ 520, and its a W (or Y) rating. If your looking to save some money, TOYO is a great brand to work with.

Obviously you will need to find a spare wheel and buy and extra tire for a spare.
