I am in the process of purchasing a set of AMG Monobloc IIs, staggered 8x18 and 9x19. What tires would work well on these wheels. I have a 300sd, which will be getting lowered on H&R springs and Blistein Shocks. Blue420sel, what size tires are you running?? Tire rack recommended 245/40/18 and 255/35/18, but I do NOT want 40s, defeats the purpose of having rims in my opinion (sidewall is too tall). And 245s for 8x18 seems pretty wide. I would prefer to run some 225s or 235s, but what would be the advantages to running the 245s, besides the obvious increased track. Thanks in advance,

JR_Rider

I've got 235/45/18s on 18x8 all the way around - treadwear has been pretty good. The guys at discount tire company suggested 235s over 245's. I have continental contiextremecontact tires. The tire guys said that if were to put spacers on the back, then they would not be able to rotate and balance my wheels and tires for free or for any price. hope this helps.

275/35 in the rear and 245/40 in the front. i have a spacer in the rear, i am guessing 10mm, or you can ask the installer just enough to push it out right before the fender . the lug nuts in the rear are 55mm and the front i believe are 40mm. good luck!

Mercedes should've included a sports package back then when we bought a W126 which included the 18inch AMG Monobloc rimz, stiffer suspension, clear corners in my opinion and then another option maybe for sports seats in the front [:D]

18" wheels did not exsist for Mercedes back when the W126 was made. The 17" 3-peice AMG wheel was considered "ground breaking" for being so large. Even 17" tires were very expensive and rare. By the way, I have this 18x8 and 18x9 setup on my coupe right now while my center peices are being powder-coated on my 17" wheels. I have 275/35/18 rear and 245/40/18. You will definitely need spacers for the rear or it will look funky. I don't have spacers right now and the rear wheels looked sucked in the back with too much space from the tire to the inner fender. Still drives fine though.

I dont really think you need spacer's... it all depend on the ET...I'm running a 18x10 in the rear and dont need a spacer.

What ET do you guys have on your rims ??

I have the identical tire sizes that you have. The wheels are 10" rear and 8.5" fronts. I believe the ET is 25 and 23 rear. AMG 2piece rims. No spacers . Like you said, the ET and rim width are part of the equation.

What is the ET on an $80K table lamp?

Gary?
I think it's about the same as the ET on a 6k fountain pen.

I'm sure you have a closetful of those as well, yet you can't manage to post a single photo of any of the cars in your 9-car signature......hmmmmmm......6k fountain pens? You'd come closer to a 6k run (as a spectator, of course).

Well, I thought we were talking about Monoblock II wheels in 18"... which were only available in 31mm offset 8" and 35mm offset 9". A 35mm offset on a W126 18" wheel is a problem in the looks department without spacers... The original post says 19x9 rears which I assume is a typo unless you are running a 19" S-Class rear Mono II which would be interesting.. My 17" wheels have an 18mm offset front and 17mm offset rear, no spacers needed obviously.

Wow, you guys running 18" AMGs on your 300SDs! I've been reading a lot of posts on this website, so much info. I just bought some clean 18" AMG Monoblock IIs on ebay, they were taken of a 94 Mercedes S500 coupe 140 body. I don't know the other dimensions, ET or width. What I want to know is if these will fit my 300SD safely? What exactly do I have to do to make them fit. Will I have problems in steering, cornering, tires rubbing, stress on suspension and lower performance? I took my 300SD for service and the mechanic told me if I use anything bigger than 16" my performance would be very affected. You guys using these wheels, can you give me your experiences so I know what to expect. If it's too problematic to use these wheels, I'll have to sell them. What AMG Monoblock IIs would ideally fit on this car, because I really do love these rims? Thanks.

I was running Monoblock II`s on my 420SEL a while back. 18x8 in front and 18x9 in the rear, both had 44MM ET. I was running H&R 25MM spacers in the front and 30MM H&R spacers in the rear. Worked and looked fine. I have now switched to AMG 5 spokes 9.5x18 ET33 and no spacers on the front, and a 30MM H&R spacer on the rear. Did have to make some minor modifications to make this set up work. I do agree with a lot of the members that 18`s are a lot of wheel for the 126, but i am happy with the looks and the ride is not to harsh for me.
