I'm ready to order a new set of ****ty Pirelli's for the rear since the front's are still good for more miles.

What are everyone's thoughts on switching over to 275 from 265 with a 9.5 19" wheel?

they should fit on the rim but will they rub?
try it, b the guinnea pig (my gf just got a slk350 and i was going to put 265/30/19 but 175 would b nicer)

That's the thing, I'm not the type to throw money away on nothing.

Here's a cool calculator to compare the sizes.
http://www.1010tires.com/TireSizeCalculator.asp

.........width..........sidewall........diameter

245 = 9.64..............3.37............24.75
265 =10.43.............3.12............25.25
275 =10.82.............3.24............25.49

You're getting considerable more width than the 265 or even the stock 245. I would only be concerned with rubbing and the overall diameter being that its .75" greater than the stock tire. I wonder if it would dramatically alter the performance? I guess you'll find out

dinko

Thanks brotha!

Hmm.. this kind of information makes it tempting for me to see just how far I can go with this car. I guess I'll give the 275's a try... wish me luck guys!

I wouldn't do it, are you that bad with 265s? You will end up throwing your esp off and the handling characteristics of the car will probably change as well.

dinko

How would the ESP be thrown off?

Dinko

Kar don

the front rim/tire will have a smaller diameter than the rears and appear to be spinning faster.

dinko

I don't see how that would matter - This is a RWD car, not a AWD.

My current set up is:

235/35/19 front
265/30/19 rear

Dinko

Kar don

Do whatever you want, ESP doesn't just monitor the rear wheels. The difference is probably small enough that it might not matter, but I wouldn't do it anyway.

dinko

Now you have me confused

Kar don

oh I didn't realize you upgraded from factory wheels. Just go for the 275s, they'll be toast in less than 10k miles anyway

dinko

haha

My order is placed... tires should be going on by the end of the month.

dsb

Hmm? I'm not sure if it would or would not cause a problem with ESP.

It doesn't matter how different the overall diameter is when comparing the front to rear as much as the difference when comparing stock to aftermarket diameter sizes.

Now, your front switch from 225/40/18 to 235/35/19 increased the diameter from 25.08 to 25.47.
The rears would change from 24.75 to 25.49.
Stock difference from front to rear -.32
Aftermarket difference front to rear +.02

Since both the front and rear are increasing in diameter, perhaps ESP wont be affected. However, if the fronts decreased while the rears increased, then it would be even a greater difference in diameter.

I, like I always say, am no expert. This is simply what makes sense to me. I'd imagine that the greater rotational differences than OE, the greater chance ESP would be faulty. Think of it this way... The ESP algorithum may not make sense as it sees wheels spinning at different revolutions than programmed. Many have tried 265 with no problems. Would 275 make a difference? Don't know.

Maybe you can find a local shop or a forum member that is discarding their old 275/30 tires. Then, you could temporarily mount them and get your answer. Or YOU can find out by taking the plunge.

dinko

I'll keep the board updated.

Cool. I am getting my wheels later this month. 19x8 and 19x10. I already plan to go 235/35 in front. Depending on your results, I might go 275/30 in rear. I am going to purchase Mich PS2's. What tires are you getting?

AMG_55

the 275 wont effect anything.
i got
235/35/19
275/30/19
the only issue is fender clearance

Did you put your brabus springs on yet? where's the pics?

dinko

Brabus Springs, Kleemann Lip, and painted sidemarkers are coming at the end of the month. I got lots of work and lots of travel this month - little time for the car.

dsb, I'm finishing the set off with Pirelli Rosso's.

dinko

Gave Brabus a ring to ask if I will be OK with 275's + their lowering springs and they said "NO WAY"

Switched the order back to 265

Totally wrong. There is a built in limtation for taller or shorter tires of about 4%. I have done this stuff a bunch of times. The 275's will work fine and in fact are a much better size for the 9.5" rims.

AMG_55

horrible

to b honest brabus na dont really know ****, but i wouldnt risk it.

AMGDAN

Dinko,
How about some Yokohama Sports- their flagship tire? The reviews are great and you can find every single size. I will buy a set of Advans A048 for the track next month.

That's why they're Brabus NA?

I'm a Michelin fan. Pirelli in second. Yokohama not even on my list

AMG_55

they r brabus na cause some sneaky **** named steve talked bodo into opening a shop in newport beach



i used avs sport (i bought my hres w/ them), they are very good but the ps2 r better and wear slower
