I apologize to all of you in advance, however, due to cost of purchase I need some definitive answers. I checked the "sticky", it showed the size below as a fit.

Opportunity to purchase set of 4 2008 E320 wheels with tires.

Size is: 225 x 55 x 16. (5x112 bolt pattern). The offset is not known. Some input I've rec'd from friends: stay with what was standard in 1994/1995 (15"). Over time, going to 16" could effect the suspension parts. None of them have my car type.

Do you agree staying at 15" for originality along with no sizing issues or prefer to go up to 16" to improve overall ride results assuming the size above fits?

Going to 16's is no problem at all. As long as the weight of the wheel is not significantly more, there will be no increased suspension wear.

The width of the wheel and the offset are important, however. Those numbers should be stamped on the back of the wheel.

Example:
8J = an 8" wide wheel

ET38 = a 38mm offset

Roughly speaking, your wheel should be about 8" wide with an offset of around 40 - 40mm, but you should check them for fit.

Greatly appreciate that piece of information. It will certainly allow me to make a more qualified decision vs. impulse purchase. Thanks again.

The attachment in one of the "sticky" posts showed, at 225/55r16 a 16x8 with 34/35 offset. Just received information that the tires under consideration are 8J 16h2 ET36. Based on your reply, 36 is the offset.

I'm confident they should fit - If the seller cooperates I'll have them mounted to be certain.

RHW

Mounting them to be sure is a good idea, I thought the recent cars had a higher offset than that.

ZedStyle

are you sure they're not from a 1998 E320? 2008 was E350, and also i'm pretty sure the standard wheel was a 17"...

as for suspension wear, i think any OEM benz wheel in 16" is not going to make a significant difference from a 15" wheel in handling, comfort, or additional strain on any parts... either way that's a lot of tire between the rim and the road...

190E 16V

E320. CDI ???

Seller reported it as 2008 E320. Had other tires with the car and decided to sell these after 2 years. Is 225 too much?

Must be off a diesel. My '05 E320 came with those. Sold em and mounted some E350 sport wheels. <3

190E 16V

Those look nice Hogan.

That will update and freshen up your Cabriolet quite a bit.

Those wil certainly be light enough and should fit. I would not expect any problems if you haven't lowered the suspension on your car.

Previous owner confirmed - diesel - you guys know your MB's. Got the tires home, they are "wide", checked basic width under front and back wheel wells...concerned about shock (spring) for the front wheels. Won't know exactly until actually swap wheels in next couple of weeks, weather permitting (Chicago weather not cooperating).

I assume I'll need to purchase New Bolts from MB dealer? Regardless, need to purchase a locking bolt for each wheel.

190E 16V

Offhand, I don't remember the width of the coupe's stock 15" wheels.
7.5J wheels (stock size?) would look small compared to 8J 16's, especially with a bit larger tires. If they clear the front struts you'll be ok, though. With the ET36 offset, there is a small chance you'll need to "roll" the fender lips, however.

Check out wheel bolts, carefully. Too short, not safe. Too long, you'll damage the parking brake! Make sure the dealership gives you the right type too.

Mounted one tire, Left Front, looks like the 225 size protrudes too much. Will wait for a final decision pending all 4 installed. For now back to standard 15". Guessing they'll be for sale sooner than later. Pictures to be provided soon also.

RHW

You "might" find that they fit in the rear,
and a different set of tires would make the fronts fit.

hogan

As in, 225 on the rear and either 215 or 205? Assuming the rims will accept less than 225. These are spring/summer only, keeping rims and giving up rotating would be the only drawback.

Pictures to follow.

You need a 7" or 71/2" width rim. 8" is a lot of work for a cabbie. Off set should be 41 mm to 46 mm. MB do a limited range of 16" X 7" or 71/2" for the Cabriolet.

Thx, I'm conceding my purchase was more impulse than logic. As stated earlier, put one wheel on the front and it was huge. Next issue...lug bolts are too long for the newer wheels. This is becoming a project that may present other issues if I proceed. Looks like they'll be on Craigslist this weekend starting at $1200.00 (obo). Not a bad price for wheels and tires (Michelin MXV4) that have never been used.

ohlord

usa has the custom lugs for 50 bucks a set.
A 225 tire is not to wide for the fronts as long as they don't have any interference turning or bumps.
You won't get any action at $1200 rims with new tires go for well below that.

hogan

Thx - another reality check. Assumed then between $800 -900 is more reasonable. Issue on the 16" is that I'm getting mixed reviews. 16" 225 x 55 x 16 is too much tire for the Cabriolet, yet others say it will be fine.

I'll check out the site for bolts...$50 invested is no loss at this point.

ohlord

R14 ball seat style so all you need is the correct shaft length and test fit them.
You aren't lowered so an 8in wide rime is only .5 inches wider and the tire while wider as said if no contact inner or outer on full lock and suspension travel you can run them.
I see you test fit one? Was it lug'd up tight and what did you mean by protrudes to far.Did it go past the fender?
Don't know your location, but if you have a discount tire outlet near by they may have the lugs needed.

225x55x16 (16x8, et36) off of 2008 E series diesel?, Michelin MXV4 Energy. Tire pressure 40/43 (front/back), max = 51psi. Read where 4 psi difference recommended on MB's. Fronts are more agressive than the rears, however, not overly stated. Regardless, pleased with the results, handles excellently. With 15" medium winds would impact driving stability - not with these wheels.

BEAUTIFUL cab...though my favorite wheels on this car would still be AMG monoblock II's.

I have 215 40 18 on my cabriolet. The rims are 8" with 40ET.
I had to space the fronts to get them to clear the struts.
The stock wheel is 6 1/2" X 15 X (47 - 51) T I know I checked hundreds of wheels to get mine to fit.
The 94-95 320E models had different wheels, brakes and hubs. The Cabrios were different again from the sedans and wagons.

Always fit the wheels (all 4) before you buy. Bounce check and lock to lock wheel turn and bounce check.

I am going to have to roll my fenders.
Always more stuff to do.
