I need to get tires. Yeah, only had the car for a year, but I like to go around turns I guess a little fast. Whatever.
I now have 205/50-17s. What\'s the difference between Z, Y, W, H rated tires. Do I really need to get a Z rated tire again or can I get a Y and be happy?
-
Z for tires that will probably go past 130mph without breaking up. That\'s what i recall. Correct me if I\'m wrong.
-
Well I\'ve only gone 115 and I\'ve only been over 100 a few times. I went 128 on the dyno though, but you don\'t get far doing that. :)
So maybe I can go with Y?????
-
Oh crap, nevermind. It comes standard with VR tires.

http://www.tirerack.com/tires/tiretech/general/speed.htm
Z=149 MPH, 240km/h and over, Sports Cars
W=168 MPH, 270km/h, Exotic Sport Cars
Y=186 MPH, 300km/h, Exotic Sport Cars

OK, so I am at V then I can go 149. Well I don\'t have a need to go 149. Would I get more mileage out of a different tire. Not really wanting to drop 800 bucks on tires every year.

http://www.tirerack.com/tires/tires.jsp?tireMake=Yokohama&tireModel=AVS+ES100&vehicleSearch=true&partnum=05WR7ES100
then how about these? They are only 100 bucks. Does yokohoma suck ass?
-
205/50 on a BMW330i? if so, are u sure coz even the 325i have a tyre rating of 225/45z-r 17 the 330i are rated at (front) 225/40 R 18 (rear) 255/35 R 18.
btw yokohama makes decent tyres in most cases theyre on par with the expensive michelin\'s (sp?) and pirelli\'s.

Sometimes. Too much width will give you more traction and friction. That can take off a few miles from a tankful but I\'d say it\'s insignificant. I\'d be more concerned with tire noise, wall stiffness and its abilities in the rain (not just stopping but turning).
Who goes 130+ mph these days? Unless you live in the desert where there are long stretches of road, anything at Z or over is not necessary.
-
That\'s what tire rack has as stock tires on my car. Let me go out and check. Damn, now I have to move...
-
Yep, 205/50-17. Dang. Now I am winded.

That\'s a problem a guy who lives next door is having with a 530. He is getting noise now that his tires are wearing. His tires are a bit wider than mine.
I like the look of a wider tire though. I don\'t want little pussy geo tires. Sorry geo owners of the world.
Rain is certainly a concern down here in FL. I\'d hate to take the foot off the gas for a wimpy shower. :)

wtf man u guys get screwed over when it comes to cars
check out the differences
ours http://www.bmw-me.com/Products/Automobiles/3Series/Sedan/specs330i.asp
yours http://www.bmwusa.com/site_layout/models/0342/0342_techdata.cfm
tho the hp is almost the same, the top speed in the ME version is 250kph or 155mph compared to the american which is only 205kph or 128mph
-
Well it\'s just a governor. You can always take the governor off by reprogramming it. Don\'t forget, there isn\'t really any need in the US to go over 70 let alone 128.

make one up ;).
-
I think I am just going to go with the stock tire. Look like they are online at 122. If BF Goodwrench has a comparible tire then I may just get them.
-
My car has Michelin H tyres and I have driven at 120mph no problem at all.
-
I was going 125mph on Goodyear Regatta 2\'s. Ride was super smooth too! Had 2 people sleeping in the back, lol
The tire tread and model is more important than the speed rating. Most enthusiasts go for Z-rated tires if they like to push the limits of their car. If you want better traction look at the sports/performance models of Michelin/BFG/Yoko/Toyo/ etc... While you\'ll get more rubber on the road you\'ll lose the full diameter grooves for traction in the rain. Worth it if you\'re a safe driver imo..
