Hi,

Has anyone fitted 295/30/20 tires on their E? Will they fit?

I've ordered the new E300de estate and as you may know, the hybrid can only be ordered with the 18 inch rims due to the weight.

The front has a maximum load on the axle of 1200kg, this equals a load index per tire of 90. This is no problem. However, the rear is 1600kg, which equals a load index of 100 per tire. As im planning on getting 20" wheels i have to go up to the 295/30 size to get a load index of 100 or more.

Wheels will fit but all depending on rim width and offset.

Kristian_TT

Im thinking of buying the E43/53 wheels or the "standard" multi spokes 20". Both are 9 inch wide in the rear.

295/30 tire will not fit 9" wide wheel. Need 10" width.

Kristian_TT

Maybe 275/35/20 is a better option?

threeMBs

Well its a full 1" (25.4mm) higher than stock so am not 100% sure since I did not try it on W213 (you will need 245/40-20 fronts too).

I know that 265/35-20 (with load of 99, which is sufficient with a bit higher tire pressure) fits the vehicle and many/most tires fit 9" wide wheel (235/40-20 front tire is required to keep diameters same/close).

Kristian_TT

Is it really necessary to match front/rear so closely on a non-4matic?

threeMBs

No, not on RWD. I suppose you can run stock's 245/35-20 upfront. Under 1/2" difference, should be OK. That's for stock 20" wheels set up.

Just FYI: if you go after market (or MB stock S-class) and go 1/2" wider wheels front and especially rear, you can run 255/35-20 (or 245/35-20) front with 285/30-20 (load 99) rear.

Kristian_TT

285/30/20 with 99 load is still not legal. It has to be 100.

So whats your opinion on 275/35/20?

Kristian_TT

This guy is running 295/30/19 on his stock 9,5 rim. So maybe the solution for me would be to get the S-class wheels and mount the 295/30/20 wheels with load of 102 in the rear.

If you care about "legality" and "safety", it is absolutely safer to run 285/30-20 with tire pressure 2-3psi higher than to run 295/30 tires on 9.5" wheels. My opinion only.

My opinion on 275/35-20 is stated above - its is not guaranteed that they fit (theoretically they should, but until someone puts them on W213, we do not actually know).

Kristian_TT

The problem is that 285/30/20 is load 99, hence not legal.

threeMBs

Understood.

295/30 recommended (a.k.a. safe) range is 10-11" wide wheels. If you want to try 295/30 on 9.5" I would find narrowest section width 295/30 tire possible (it varies by manufacturers). I would also consider rational of using 295 width tire on a car.. well frankly short on power to be useful on.

Regarding 275/35-20. In the US, I would buy one mounted/balanced then try it on. If it fits great (buy the rest), if not I return it back for a small fee. Tire Rack in the US is the only place I know of that allows this. I do not know if you have this ability in EU (assuming you're in Europe).

Worse case, you'll have to do with 19s

Somethings do not add up.

Front axle load of 1200kg is 2640lbs or 1320lbs per corner which correspond to load index of 90 as you stated.

However, rear of 1800kg is 3960lbs or 1980 per corner which correspond to load index of 104!

If car is delivered with 100 load tires, you'll be more than safe with load of 99 for 285/30 or even stock's 97 for 275/30.

According to above EU site, there's no special provisions for E300D.

Kristian_TT

Sorry. Should have been 1600kg.

The problem is the legality, not the safety. I could get in trouble with insurance f.ex.

Its the new 300de (hybrid) estate, hence the wheight and high axle load.

Kristian_TT

The s-class rear 9,5 et38 wheels will stick 21mm furter out. Will this be flush or to much?

vic viper

Wont work.

Kristian_TT

You sure? See comparison with yours:

Kristian_TT

BTW, its was 17,4mm difference, not 21

threeMBs

Do not agree with stated opinion that it won't work. I just posted within last week that I'm running 275/35-19 tire (I selected tire - Falken FK510 - with the widest section width available) with 19x9.5" et38 wheels and it is 100% flush with zero poke. Pictures were included.

If you run 275/35-20 that you want and it clears fender edge, you will be 100% flush too.

However, if you run 285/30 I suggested (which you probably won't), then a mild poke of about 5mm or so will be present. To mitigate, select the narrowest section width tire available - Sumitomo HTR Z 3 - and your poke will probably be eliminated.

Edit: I still stand by suggesting not to mount 295/30 tire on 9.5" wheel, but if one does anyway, then visible poke of as much as 1/2", depending on tire's section width, will be present.

ET38 sounded low but yes I stand corrected.
