Regarding my GLA 45 (2015), sometimes i have a weird noise coming from the wheel/tire when I try to turn the wheel (slowly). first noticed from backing out from parking spot. Is this the friction between tire and the ground? could it be alignment? or specifically the tires are too hard in this weather? or could it be the 4matic? or low profile tires?

P.S. im from canada, its about -2 here right now in Toronto. The vehicle has 13k km on it now. im new to MB, just came from a 2012 328i xdrive coupe, never experienced these kind of handling issues.

update on the issue: The noise disappeared when temperature reaches more than 15-17c and above. for those who wonder. i was told by MB dealer that the 20 inch is a set of all season. godbless these crap sales.

I had the same issue Michael. It's the tires sliding across the ground when the wheel is turned 1 or more turns. Once the tires got up to temp the noise went away. I just replaced those summer tires for Michelin AS3+ 255-35-20. These are amazing All Season tires, probably the best to date. You will need to put wheel spacers on the front though, in order to accommodate the bump in width. The only downside is I can't get it to drift anymore, these are just too planted.

255 is too wide. im thinking about switching to bridgestone pole position s04 245/35/20. but even that might be wide for front.. i dont like the continentals, the wear is too fast.

245's work just fine on the GLA45. I have snow tires that width and they were not a problem.

Would anyone be so kind as to take some photos of a 245/35/20 tire setup on the MB 20" black multi-spoke rims please?

I am thinking if I should pay quite a bit more for the hard to come by 235/40/20s or change them to cheaper 245/35/20s instead. I am actually concerned about how much more the edges of the 245/35/20s would protude out of the 20" rims, even the height difference with the 245/35/20s being 8mm taller.

Much thanks!!!

really? the 245/35/20 r that much taller?

235 × .40 = 94 mm sidewall height.

245 × .35 = 86 mm sidewall height.

So the wider tire would be 8 mm shorter.

 

[Azrielsc]

Ah, my bad. Got it in reverse!

 

[pico33]

235 × .40 = 94 mm sidewall height.

245 × .35 = 86 mm sidewall height.

So the wider tire would be 8 mm shorter.

Is that mean, the tire is 8mm x 2 (because the diameter) = 16mm smaller?

 

[Wayne]

True. Diameter vs radius.

I don't have the figures here right now, but if I recall correctly, the rolling diameter on the 19 inch wheels is closer to the 245 wide 20 inch option.

 

[pico33]

Does 245 40 also fit on the 20" with no trouble? or need to use 245 35 for 20"?

 

[fatalus]

245/40 20 definitely fits. Someone in this forum has had these with no problems at all. Actually 245/40 20 are much closer to the OEM dimensions than 245/35 20.

wat tires are you looking into? i think im replacing these continentals with bridgestone s04 poleposition, but would like to hear more options.

 

[Wayne]

I'm a Michelin fan. There is a close fit on the MPSS.

Yes, Yes, That's the exactly what I am looking for too!

The overall review ratings look pretty good on these. I've loved the three sets I've had on my 997.2 C4S. Only problem (at least with the sizes I need) is availability.

I will definitely buy Michelin Pilot Super Sports in this dimension.
