I'm coming up on 30k miles and the OEM tires are shot. Any body out there replace their OEM tires with something other than Michelin and really like what they got? I'm interested in something with about the same tread wear. Thanks in advance!

 

Potenza S-03 Pole Position, treadwear will be lower :o

You might like Kuhmos, Toyos, or RE730s

 

What about stock size all season tires?? Not high performance summer tires.

 

high-performance allseason

Yokohama AVS dB 235/17/45 on moda r6 17x7.5 wheels

they are nice and a little wide. excellent handling.

 

I bought Bridgestone Potenza RE730 225/45 17 yesterday, will report back after they get here (mail order was $60/tire cheaper)

I went with the 225's because they fit on the stock rim and I don't pull a lot of G's when I take turns. only sometimes

 

You made an excellent choise with the RE730's/ You'll notice a huge difference right away in handling.

Expect a rougher ride, and they get a bit noisy after about 10,000miles. Rotate religiously and you may sneak 25,000 miles out of them (I have 20k on mine now and they are about to be replaced.)

Also note, as I hope you already know, that there is no snow traction at all with these tires. In the rain they are very good when they have tread on them (unlike mine).

Plus, because they have a slightly smaller rotating diameter and are stickier you will lose about 30 miles per tank of gas.

 

225/45/17
what is the 225?... 45= how big the side wall? and 17= rim size?

 

225 is the tire width in mm, 45 is the aspect ration of tire width to tire sidewall hiegth.. The side wall is 45% of the tire width.

 

what tire width's fit our 17in rims

 

Here is what I use to figure out what tire/wheel combo works well.

((Wx(P/100)x2)/25.4)+R = H

W = tread width in millimeters (215, 225, 235, etc.)
P = tire profile in per cent (35, 40, 45, 50, etc.)
R = rim diameter in inches (16, 17, 18, etc.)
H = overall tire height in inches

i.e. 215/50/17 = W/P/R = ((215x(50/100)x2)/25.4)+17 = 25.465

The answer will be the overall tire height in inches (or at least pretty close).

Speed Rating = MPH, KMPH, Typical Use
N=87 MPH, 140 km/h, Spare Tires
P=93 MPH, 150 km/h
Q=99 MPH, 160 km/h, Winter, LT Tires
R=106 MPH, 170 km/h, LT Tires
S=112 MPH, 180 km/h
T=118 MPH, 190 km/h
U=124 MPH, 200 km/h
H=130 MPH, 210 km/h, Sport Sedans
V=149 MPH, 240 km/h, Sports Cars
Z=149+ MPH, 240+ km/h, Sports Cars
W=168 MPH, 270 km/h, Exotic Sport Cars
Y=186 MPH, 300 km/h, Exotic Sport Cars

 

That can vary by the tire manufacture. Generally speaking our CL-S rims can handle 215 (our stock tire), and 225, probably most 235's (but you should really check with tire manufacture or someone like TireRack. YMMV

 

215/50-17 (stock)
225/45-17 (will fit, but is throw speedo off a tad)
235/45-17 (generally 1/2" too wide for 7" wide rim, but some makers and/or dealers will work with you.

One member put 235/40-17s on the rims (manufacturer of tire wanted an 8" wide rim).

All of the above is based on a 17" diameter x 7" wide rim.

BTW -- the alignment of a 235/45-17 (depending on tire make) on the stock rim can cause scratching to the wheel's clear coat.

(There is more to all this like load rating, but...)

 

Thanks; here in Dallas we get ice a couple times during the winter months of Jan and Feb. No tire works well in that. Hopefully the gas mileage won't change that much. I keep a detailed log and will let you know. Did you take into account the speedometer error the new tires create. 30/400 = %7.5 seems kinda high

 

this should go in the faq =)

 

AS a note -- the stock tires on the CL-S are considered to be "green" tires -- extremely energy efficient due to their high silica content.
