Can I change 19 to 18" Wheels?
Hi everyone,
This is my very first post on the forum, so I'm glad to be a part of the community. I have recently purchased my first ever convertible vehicle - a 2019 E450 Premium Plus. Rare in the UK as it's usually raining haha. I love the car but there is one major issue for me - the ride quality on the roads here is terribly harsh and uncomfortable. I was expecting an E-Class to be super comfy, but I was really upset after a drive down some of our roads here. After some thinking, I realised that the car has 19" wheels shod with run-flat tyres. If I can soften the ride I would be so happy with this car. So what I would like to know is - can the E450 take 18" wheels? The brake callipers look pretty meaty on the front wheels, so I wasn't sure if 18" will fit. The local Mercedes dealer here didn't know, without me taking the car in one day and letting them see if they can physically get a wheel on. So I ask - does anyone here have an E450 with 18" wheels? I'm sure if I can install the 18" wheels and non run-flat tyres the ride quality will be transformed.
Thanks very much.

I removed the 20 inch wheels from my E220d and installed 18's (AMG 20 inch wheels came standard on E Class's post 2017 in Australia).
As long as you get the offset and tyre diameter correct.

First of all, welcome to the forum sugarat.
If I had to take an educated guess, I’d say that 18” wheels should be no problem. We have a 2019 E450 Wagon and it has 18” wheels. The larger wheels and deeper sidewall tires will help, but you will see the biggest improvement in ride quality by going to 18” wheels, dumping the run flat tires and going with a nice set of comfy, conventional tires. I highly recommend the Bridgestone QuietTrack tires, which we have on the wagon. You might check with www.alloywheelsdirect.net, as they have all that info. Talk with Tony. Great people there. Best of luck to you!

Anyway, another way to confirm is to check the fuel filler flap. It should list out all sizes suitable for your specific car. My bet is you will see both R18 and R19 listed there.

So I did go to a Mercedes dealer local to me here and sat down with them. Long story short, I have got a nice set of 18" 5 spoke Mercedes alloy wheels on order. They will be fitting them with Pirelli P7 tyres and new TPMS sensors. Blimey it really wasn't cheap for a whole new set of wheels and tyres, but I'm sure it will be absolutely transformative for the ride and comfort. I can't wait!
Thanks all :-)

So our wagon has 18" wheels and the Pirelli P7 RunFlats; I thought I would not like them, as our E450 cab has 19" and we just changed to Michelin Pilot Sport A/S tires from Goodyear runflats. Was I wrong, the ride quality of the 18" with the Pirelli runflats is more than acceptable, and I will admit to being shocked to be saying that. I have altered my opinion of the 18" runflat combo; it works for us.

I was assured that I was getting 18" wheels with non-RFT's, so I'm assuming these are normal tyres. He said they are rated A in ride quality and road noise, so I was like 'Sure, go ahead'.

Couple of thoughts. My 2019 cabriolet came with 20in Runflats. Comfy is not a word I would use. My wife’s 300GLC has runflats with much more sidewall and it really isn’t too bad. I switched to 19 in winter tires , conventional, not runflat. BIG difference in ride. Very nice, though not S class nice. But this is a sporty car. I bought a flat repair kit from Griots Garage. It is a mini inflater and TPMS safe sealer all in a neat little case for my trunk. In case I get a flat because we have no spare. Let us know how it works out!

Didn't finish my thought; on the E450 cab change from 19" Goodyear runflats to same size Michelin Pilot Sport A/S, there was a significant improvement in the ride quality, as well as reduction in noise from the tires; we experienced a similar scenario when we changed our now departed R231 SL550 from Continental 19" runflats to Michelin Pilot Sport A/S. We keep a TireRack inflator / slime kit in the boot and motor on. But IMO, there is an overall improvement in the vehicles when moving away from runflats, my sample size 2 times, both 19" rims.

I’m sure this has probably been posted before and it’s all about the All Terrain, but read the comments about wheels & tires. With the car companies, it’s all about a sexy look, who cares about ride quality, right?

I have a 2019 E450 Luxury with the standard 18" wheels and Pirelli RF P7 Cinturato tires and find the ride extremely soft and pleasant. My personal opinion is that going from 19" to the standard 18" wheels will solve your problem. I think the difference in ride between the RF and non RF on 18" wheels is marginal and the added safety in the event of a flat that the RF give you is well worth the price. I recently had to replace two of my tires because of bulges in the tires and choose the P7 RF and not non RF. If it matters, at 20,000 miles I had 7/32 of tread left on the rear and 8/32 on the front: the new tires have 10/32 so I expect about 40,000 miles on the Pirelli RF..
Hope this helps

Thanks, i have heard that and hope I never have to worry about it!! It was so cold yesterday and I was thinking that just to get out and mess with sealer and a compressor would be no fun…was second guessing the no rf again. Lol.

Just found this video.
It would seem that the sealant remains in a viscose state and can be removed if done relatively quickly after the flat. Just make sure when you have the tire repaired that you notify the tire dealer that you used the sealant. The video indicated that the TPMS must also be removed and cleaned as well as the wheel and tire.
I have RF and see no reason why the sealant cannot be used in a RF. I would rather pay for the cleaning of the TPMS, wheel and tire rather than the cost of replacing the RF!
Hope this helps.

RF are exclusively useful if you have got a small puncture, but in case your tire has been damaged by a stone or something in the like, RF are totally useless I have had already the bad experience
a couple of times !
RF tires make more noise and are uncomfortable.
I cannot understand why so many dealers try to sell RF tires ?
