Factory size is 215/65/15. AMG Aero 8x17. +11 offset.

My 560SEL will be lowered 0.75-1" at the front only. I was thinking 245/45/17 all round.
What have you guys had experience with suggest, and why?
Would appreciate feedback/comments thanks.

I have 235/45/17 Pirelli P6's on my C126. The car is lowered with H&R springs and the fender are rolled. No rubbing and the setup looks great!

OE size is 205-65-15, so with +1 ratio would be 235/45/17. Based upon the AMG sizing it could be 235/40/17 up from the 225/50/16 generally found on AMG cars. IMO

Thanks guys. I hear you on the 235/45/17 and they do look great but the instruction manual for my 1990 560SEL says that the specified tires are 215/65/15. Going to 235/45's will mean a change in the speedo reading of 2.6%. Going to 245/45/17 will mean a speedo reading change of 1.2% which is almost negligible.

The width of the 245's attracts me and they should fill out the guards better. I really want to be rid of the AMG replicas but want to make sure the tire selection is right. Then there is tire brand selection .....geeeez.

Anyone have 245/45's with Aero 1's?

i have 245 45 17 with amg 3 piece in front and 275 40 in rear

im thinking about going down to 235 45 in front and 265 40 in rear, once i lower the car

right now, that i have my fenders rolled in rear, i have no rubbing over those yump bumps , i just wanna maintain that aspect when i do lower, if i do, hence i was thinking about the 265 in rear set up and i would have to match with 235 in front

what suxs is tires choices is limted with that setup for me

I believe the differerences are seen between 560 and non-560 fenders. Its very slight though. There have been past threads on it.. I think by Damon?

The difference in the fenders is only the wider arches on the euro 560. Us versions of the 560 don´t have them. Therefore they have 205 tires instead of the oem 215 on the euro version.

Gen I and non 560 Gen II fenders are the same and interchangeable.

Is the fender difference true of both SEC's and saloon versions of the euro 560? I was told recently that only the SEC had the slight difference, not sure if thats true though.

Hey guys and gals. Thanks for your input earlier. I left it a bit because I was concrentrating on getting the tyres for my OZ rims right. It's been a while but I'm now ready to take off the AMG OZ rims and install the AMG Aero 1's. The OZ rims are my special occassion wheels. I'm very happy with my tyre selection for the OZ rims now...update will come soon on the thread for this.

Quick q for those not wanting to read on - Should I go for 235/45/17 or 225/50/17? Anymore pics with both installed on 17" rims on a w126?

The AERO 1's will be used on road trips. We have just about got to Summer here now and Optimus Black Pearl (OBP) will be used more often for the weekend trips. Never take a Hyundai or another compact car on long trips. Geez the crappy seats and bumpy ride make your [email protected]@ sore, lol !

Anyway, I digress. In two weeks I will install the Eibach springs at the front only. This will just give the SEL a very very slight rake at the front. This will also fill the tyre/fender gap.

The tyre selection is almost a nightmare. I would like to go to Michelins and be done with it. My local tyre guy has got Pirellis on special so it could be those. Otherwise there are others ike Bridgestone/Hankook etc. For the US guys, I'm looking at what you would refer to as an all season tyre.

The question : I still have not decided on the size to go for. I prefer them to be all the same size all round for rotation purposes. The thing is the size.

The factory size for my 560 was 215/65/15 and I have a preference for 225/50/17 as this gets close to the rolling diameter. The difference is 661mm (factory) and 658mm (225/50's). This is a nice upsize. The important thing for me is comfort on the long trips but I dont want the car to be wallowing at every corner. I dont drive my w126 crazily but like to have that confidence that if I have to make a sudden maneover, the tyres will do their job. Most trips will have my family onboard as well.

235/45's are another option but these have a lightly lower profile and I'm sure if my car will really suit that look.

Some of the Aussie guys might be able to help with this. Older Holden Commodores/Falcons come to mind on those beaut Aussie open roads.

For anyone - How have you setup your w126 for touring?

Thanks in advance as always. BW is incredible for w126 stuff.

Here are the "official" AMG docs for the Aero I wheels - Conversion from stock wheels and also the German TUV specs. Note that you have the early verison Aero wheels (not the ////AMG) and need 12x1.5 lugs with a 33mm threaded shaft. Also, the "correct" tire size is 235 45 17, per the attached.

Thanks alydon,

I have those docs and remember seeing the tyre size.

It appears that the tyre size recommended by MB is 235/45/17. The speedometer correction is recommended for 560's. I guess most w126 with AERO 1's were AMG kitted back in the day as well and may even had AMG lowering springs installed.

I figured by going to 225/50 tyres I would not need to correct the speedo. What do you think?

If you have a GPS, check the accuracy of your car's speedometer currently. If accurate, then choose a tire that has the same or close to same rolling radius as your current tires. If your current speedo is inaccurate by some %, play with the rolling radius on different tire sizes.

Good point Al. I found out last year that most European tyres are larger than Japanese/Korean tyres. So a Euro 225/50 could likely be larger than a Japanese/Korean 225/50 !

I'll put the standard wheels on and get a starting point from there.

Any images of w126 with 225/50/17's?

I am running 235/45/17 with no issues with the speedo. I can change to the 15" stockers (205/55/15 I think) again with no effect of speedo calibration.

I dropped my car close to 2 inches so my last 234-45-17 rubbed. They are now 225-45-17 and not a problem.
