Hey guys...need help urgently...

I need decide which SIZE tyres should I get for my 19's Carlsson 1/16 Ul wheels for rear wheels...

I have 2 options either to go for REAR for 275/35 at the rear (factory reccomended) or 285/35 ???

My car is lowered via Carlsson lowering module...

I think with 275/35 the wheel would show up more, due to smaller sidewall, but with 285/35 car would have a better grip...

Anyone treid both sizes and can comment...the difference...

Looks, fit, drivebility, grip and other ???

Anyone actually have any pics of those diff sizes on same wheels ???

Thanks

275/35 is too tall.

If you are doing a 245/35/19 in the front, you can do either 275/30/19 or 285/30/19 in the rear.

If you are doing a 255/35/19 in the front, you should do a 285/30/19 or 295/30/19 in the rear to keep the tire heights the same.

We cant recommend rear tires without knowing what front tires you chose.

How about with 275s in the front??

Bigdot

go as fat as you can in the rear,


as for the front, be careful, fat tires can introduce MORE understeer.

I didnt want to say anything before but I think 275 in the front is a bad idea. You wont be able to match the height in the rear unless you run the same 275 in the back. That would in effect throw off the balance and handling of the car completely.

255/35/19 is the biggest width tire I would run in the front and 295/30/19 is the biggest I would run in the rear.

275 is too BIG in the front...

On an E55, a wider than 245 section width will produce a phenomena I refer to as autopilot. In other words, the larger contact patch would tend to follow every groove on the highway. In effect, a wider section with would also produce more roll resistance. Probably why dragsters apply skinnys up front. As far as your rears go, I would remain as near stock diameter (25.30) as possible: (25.49) 275/30/19. In a word, vrus is on the right path; the key to aftermarket plus sizing is balance. Just my three cents (inflation).

I really wanted to go with a 285 or even 295 when I went to 19s but all the wheel and tire experts dissuaded me. 275/30 rear was the final result.

Rafal

I will second that. Just be sure to order from Carlsson the correct spacers for rear offset of ET38 if you want the 285 or you will rub your rear fender trailing edge where the rolled metal meets the sharp plastic bumper.

WHY ???

Guys... I made mistake I was talking about 275/30 or 285/30 for REARs...NOT 275/35 or 285/35 sorry...

I am scared that with lowering module 285/30 might rub, had that on my S-class...

I have a choice of either Pirelli 275/30 or Yokohamas Advan Sport 285/30... Front ones are 245/35 any of those brands, since bigger doesnt fit with lowering module...

I have till Monday to say my final word...

Anyone has pics 275/30 vs 285/30...and do 285/30 really grip much better and provide better traction then 275/30 ???

Rafal

285 will fit better on your 10" UL's, 275 are matched to 9.5" wheels.
Why do you have issues with rubbing on the front fenders? Carlsson makes all wheels with ET40, if I am not mistaken, and then supplies bolt-on spacers to suit each model MB. Lowering your car increases the negative camber so much that the lower it sits, the wider the gap becomes between the top of the wheel and the inside of the rolled fender.
You will have no problems at the front if you keep your ET30-ET35 with either 245 or 255 tires. They won't come near the control arm bolt at the top either. I have both sets, 245/275/19 and 255/285/19. The 285 grips better, but there is a bit of tram-line or wiggle as the car hooks in. They look great!

E55 RUSS

All tuners told Me that 255/35 will rub with lowering...but 285/30 at rear would be OK...


Can you really feel the diff btw 275/30 vs 285/30 in term of tractions ???

I think 275/30 would look better on 19x10...

Anyone has any pics ???

dragonAMG

go 285/30 rear. You'll be fine.

E55 RUSS

Looks like 285/30 is best combo...

Sent e-mail to my wheels dealer to change to 285/30...Yokohamas...hope I am making a right choice...still not too late to change back

Why do all those people with lowered E55's (Vic55 and others) run 275 at rears...

dragonAMG

I'm running 285/25/20 rears and my car is lowered. I wanted to go with 295 rears but ultimately decided against it and went the conservative route with the 285's. 285/30/19 will be fine.

BTW -- I too went with the Yokohama Advan Sports.

Torquey55

295 Michelin PS2 definitely rubs on my car. The "wiggle" is a real pain. I should have gone with 285 or even 275.

Rafal

BRABUS EV12 and other 211's use 255/35/19 and 285/30/19, and they are MAJOR tuners, so there...
When you put a 275 on 10" rim, the tire side wall is no longer vertical but it begins to lean like a steep roof. It's your choice and it seems your mind was made up before you asked for advice. You really just want a pat on the back. Either way you are OK with both these choices.
There is no rubbing with 255 if the offset is correct. I even put on ET25 255/35/19 from CLS55 and had my negative camber reduced by 0.4 deg after lowering and still no rubbing. Who are these genius tuners advising you?

Rafal

Here a two close-up shots of PS2: Front ET35 255/35/19 and Rear ET38 285/30/19.
Rear wheel arch shows masking tape to check for rubbing. Ultimately, the wheel-over-curb full compression test left a three-credit-card gap between the tire and the inside of the rear fender. I did not bother with the front, the gap is so big, even though I had wheel alignment done to correct the negative camber after lowering.The car looks a bit high at the front, because I just parked it and it popped up. Normally it rides 1/2" lower.

E55 RUSS

Thanks man...gone try to get 245/35 front and 285/30 rears...if my wheel man didnt make put tyres on the wheels already and sent them to my dealer...

Those genius are some respected "Sponsors" on this board...If it would be one then I would ask, but all of them were telling ME 255/35 might rub on front if the car is lowered...and 285/30 will be fine...

Rafal

I understand your point of view, just remember, that being a "sponsor" which translates here into "vendor" does not automatically make one as wise or as impartial as King Solomon.
You have chosen well, as on 8.5" front rims 245/35/19 will have a diameter of 654.1mm and on 10" rear, 285/30/19 will be 653.6 mm in diameter. Also, your rear rim is 38mm wider than the front and the rear tire is 40mm wider than the front one. Who could ask for a better match?! Post some photos, those UL's are fantastic, and you will love the handling!
When the rim differential is only 1"/25.4mm (8.5"F and 9.5"R) I would still go with 255F/285R like BRABUS EV12. BTW my PS2 both came in at 660mm diameter after mounting.

OzE55

Rafal, you know your stuff..... but why go 255 at the front?
Apart from looks are there really any advantages in going wide at the front? Why not stay 235/245 on 8.5" rims? Less rolling resistance.

Also, is the 660mm a rolling diameter or measured static with the wheel/tyre not under load? Different companies quote sizing in different ways - makes it confusing.

I understand the speedo measurements/readings are off the rear wheels, if thats so it doesn't really matter what the rolling circumference is at the front, apart from looks??

Thanks.

Rafal

660mm static at 35psi.
255/285 : better front grip= less understeer,better braking, (that is a price of higher rolling resistance), better rear grip= less ESP interference (hardly ever), same diameter Front and Rear, same amount of rubber sticking out over F and R rim, same wall shape front and rear, both tires fill the wheel arch better, they look hot, speedo now 100% accurate,
the whole car looks more solid down low, as if the visual centre of gravity was lowered, higher load rating matching the XL of OEM 18", must I go on?

And then, there is the BRABUS EV12 "land speed record" on the same size tires...

Last, but not least, if they are good enough OEM on mechanically identical CLS55, for which people pay a 10% premium, why not on E55?

E55 RUSS

Where are the pics with your new wheels ???

E55 RUSS

Thanks man...Cant wait my self...

OzE55

I don't disagree, but, do you really think people can tell the sectional width is different on fronts. At least on rears they get a good look from the back.........after they see the 4 'drain pipes'.
Is your experience that the wider fronts improve handling? Because if they're heavier they will worsen the ride and (theoretically) cause "tram-lining"?
I dont think the land speed record is particularly relevant in the land of double demerit points.
