WHAT TIRE SIZES CAN YOU FIT WITHOUT ESP OR ABS ERRORS?
SL65 2004 model comes out with 19" wheels, I have gone up a size to 20" now am getting ESP and ABS warning codes on dash, called local wheel shop they say wrong size, what can I fit onto it without my car going limp mode. I have noticed many people have various sizes on there cars. How did you get away with it ? without the car not spitting out codes?

That's really weird. What sizes did you have and what do you have now?
Did you mix the rear and front tire sizes?
MB setup fits up to 255/30/20 fronts and 305/25/20 rears. But i bet guys went beyond that

at moment i have 255/30/20 on front which is okay, the rears are 275/40/20 , I've been told the rears can be 305/25/20 , 295/25/20 or 275/30/20 . But I have noticed members on this forum with all types of sizes how do they get away with it ? some people are running radials on the rear! this is what i wanna do to, to get maximum traction.

idk, i guess there's a certain size match up for the fronts and rear when you're changing tires. I just bought last sunday some 20'' and going monday to put them on and see if anything pops up. The sizes that are on the wheels are 245/35/20 fronts and 285/30/20 rears (hoped the rears would been wider )
Btw just made some research on the web - here's the issue
You're running 255/30/20 front. The total tire height it's at 92mm.
Now when you're looking at your rear ones you have 275/40/20 - the total tire height is 106mm
If i'm right then the car recognizes the new levels of your suspension as errors, and throws up the codes. Your rear suspension apparently is 1.4 cm taller.
Usually when changing tires you should try to keep both front and rear at the same ratio as it was previously.
For 255/30/20 front i'd say the sizes you should be looking at is 285/30/20 (99mm) or 305/25/20 (97mm).
check with a good tire shop or make some research on forums, you'll find lots of answers

Idk, JUst mounted today my 20'' and they fit just fine
Actually i was thinking did you have your car scanned? To see what codes exactly you have? Because there might be more than 1 thing that triggers those two lights
Do that for start, maybe you'll get some answers

Comparison of oem tire set to your choice of tires:
With oem standard tire sizes the front wheels are slightly larger. So the rear wheels rotate at 1.008 times the speed of the fronts or 0.8% faster.
With your set up the rears are larger than the fronts. So the rear wheels rotate at 0.909 times the speed of the fronts or 9.1% slower.
Comparison of oem front to your choice of front & oem rear to your choice of rear:
Front tire size is nearly identical with you choice being 0.9961 percent smaller.
Rear tire size is inverse and a greater offset being 1.1038
By doing the math the configuration that you have chosen is 10.77 % off from factory design.
This being said and if it is possible (don't know the brand of tires you have) keep the fronts and get 295/25/20 and remember that all your choices need to be XL to handle the weight of our cars.

And play with tire pressure, for better ride. The guy at the tire shop pumped mines to 38 all around. Driving on hot asphalt kicked it up to 42 - i was driving like on rocks! Awful experience. Lowered to 32 fronts and 36 rears. Much better, but still planing on taking it to 30 / 34 for an even smoother ride FWI - door sticker says 26 fronts and 29 rears - of course with stock wheels

Did the lights turn off? If so - pics are due with new rims

But as Welwynnick says lets start with an offset. Mines are 245/30/20 offset +15 fronts. But you should be able to work up to 25 or so.
You know what's up with the offset, right?

Mines are 245/35/20. Double checked the size. Took a pic also. Look how much space i have between the tire and fender. So i'll assume you lowered the car, that's why

sorry i think i was not very clear, what i meant was is the guard rubs on the tyre over road humps and steep driveways or crests in the road , it rubs for a second if that

Did you lower the car? That would be it ironic to lower the car and drive in HIGH setting after 😄
also depends on your tire width, I'd say it should be greater than 9J, is it?
