Close.... $230 for the rear...$186 for the fronts.

I will not get the S03, my current ones are good enough (I hope mine will be cheaper than S03)

Nope...about the same...

NAWWWSSSSS ... maybe time to skimp to japanese tires lol

The yokohama AVS ES100 are supposed to be a good tire. My unlce has em on his 2000 3-series on the M-sport rims; 225/45/17 and 245/40/17 in the rear. He likes em a lot.

Yeah, I'm not sure, but I don't think high performance Z-rated tires are really needed for that car...do you drive very aggressively or drive over 100 or so consistently ?

Edit:

OT, but I hate when car manufacturers use different front and rear sizes....it makes rotation impossible...especially with high performance tires which are usually directional.

I don't think you can go lower than Z with 18s. I know BFGoodrich had H rated 18'' tires but they sucked (I used to have them). I agree with the different sizes in front and back. Most people won't really benefit from it. Also, directional tires don't provide any significant advantage in the rain over non-directional. I remember an article in tire rack where they ran the tires in the opposite direction with minimal lost of traction.

the tires in that size for the bmw 330ci only come in like YR, WR, and ZR speeds (except for the V rated winter blizzaks). The car wants sticky tires. You want sticky tires.

Just because you don't drive over 100 or agressively doesn't mean that you don't need those tires, Z rated tires are designed with higher heat capabilities and better grip etc in mind. Tires can make all the difference in the world on how your car handles. I don't like getting cheap tires. I'm a big advocate for getting the best tires you can afford for your car. Tires are not something you want to skimp on.


EDIT: oh and in the case of the BMW 330ci 18" wheels, the wheels size width is different front (8") and back (8.5"), so rotation couldn't happen even if tires were the same, unless you wanted to mount and unmount the tires each time, which could weaken the sidewall and tire bead.

Yeah, I was worried about that....I'm guessing they are figuring that someone with 18" rims is not going to be looking for your basic all season passenger tire.

I disagree a bit on the directional tire not being any different running backwards... I had a major problem once with a new set of Dunlop SP8000's, and I kept having traction issues at even very low speeds. Checked them out and found out the rears were mounted backwards.... :|

Also, look at a wet traction performance tire like the Firestone SZ50...if you ran that backwards, the water wouldn't exit the tread right....IMO.

what are you talking about?? Bridgestone is japanese.
Kumho are one of the cheapes 18'' tires you can get.

oh my bad didnt know bridgestone is japanese...

how much are kumho tires?

Also I didnt CHOOSE z rated tires, it simply came with the tires..

and no I dont drive hard.. well not always

I agree...but to a point. I mean yeah, you will gain some traction over a "harder" tire, but you also have tradeoffs like treadwear and the like. I'm not suggesting he go out and get four Pep Boys specials, or go ultra cheap, just maybe a slightly harder tread. Another thing to think about is winter driving. A lot of nice Z-rated tires can be almost un-driveable in snow and ice. I seriously doubt on a 330ci it will make *that* much of a difference...it's not like it has a ton of HP or Torque... (not knocking your car...it's a nice car z0mb13)

I hear where you are coming from though....

BMWs are known for their handling, not power..

and yes this is the best handling car (in its class) I've ever driven. I drove a buch of cars before I got this (the g35, audi, c class, etc) and this is the one I like the most. I think the tires helped a lot in that aspect.

Also I dont think the 17inch tires come with Z rated tires... they only give Z rated on 18 inch tires (which comes as an option)

The power is all to plentiful for me, I dont see the need for a 260 HP + cars. This car's power is enough.

Nope. Although I would consider myself somewhat knowledgeable about tires; I can spend like 4 hours reading/researching about tires, but don't seemed inclined to do my calculus HW. I'm just a freshmen college student who is trying to study and go through with an mechanical engineering course. My ultimate career goal is to become a professional race car driver, for like the ALMS. I wouldn't mind being an engineer for a team or even head technichian.

z0mb13-

I was not knocking your car AT ALL. BMW's are nice, and are some of the best handling out there. I drove a friends 2002 M3 a few times, and it was a pleasure. The car drove like it was on rails.

The mention of torque and horsepower was not a dig on your car. For instance, on my Mustang, I have modified it fairly heavily over the years, and that combined with stiffer suspension, light rear end, and the added HP and torque makes me need Z rated or better just to get traction under moderate acceleration. I was just saying that your car would likely not have that issue if you got a slightly "harder" tread, and you would get a bit more tread life.

This is all a moot point anyhow since it appears there are no sub Z rated's in a large size like 18"+.

yes I did look at the tires, and it only says maximum pressure of 51 psi..

My tires are currently at 25 psi, is this too low?

I usually run my tires at what is on the sidewall, as they are not the OEM tires anymore. 25 psi is pretty low IMHO.

You = teh st00pid. Run at the pressure specified in the manual. The pressures on teh sidewall is the MAXIMUM pressure the tire can take.

Go to tirerack.com and read the reviews. Also, their prices are VERY good.

Or sometimes it's in the glove box if it's not in the jam.

These pressres only apply to the original equipment tires. I would suggest running your tires at their maximum listed pressure on the sidewall as this will yield the least rolling resistance and the best gas mileage.

I used to have the Yokohama AVS ES100 and replaced them with Pirelli PZero Nero M&S because I moved. Better grip, even being all seasons, and much quieter too.
