What size tyres for my wheels?

I was looking to change my wheels, but may stick with what is on there. They are 8Jx17 front and rear, so what size tyres should I have? The fronts are currently horrible budget 215/45s and the rears are 225/45s. I'm thinking I should have 225/45s front and rear. Does that make sense?

For tyres I'm thinking Dunlop Sportmax RT2, or Goodyear Eagle Asymmetric 3, or Avon ZV7, or Uniroyal Rainsport 3. Any thoughts?

All feedback much appreciated.

Cheers

Andrew

A lot depends on the offset of the rear wheels (at least 30mm) but with a 225x45x17 on front I'd like a 255x40x17 rear. Both are 25" diameter. Those sound like aftermarket wheels since Merc usually staggers them.

Can compare them here - you want close (within 3%) of the same diameter.

ps Michelin/BFG/Uniroyal are the same company and over here Uniroyal are the "low line" tires. My requirements are for wet traction first and for a performance tire I like The BFG Comp TAs

Thanks for the responses. They are aftermarket wheels - were on the car when I bought it. Interestingly though, one of the options Black Circles gives for my reg number is 225/45s front and rear. The current 215s on the front look narrow on the rim and I take it 225s sit well on a 8J rim? The 225s on the back certainly look like a better fit.

Whilst I know that Mercedes usually offered staggered rim sizes, my question is whether with the same width rims it is a problem to run the same width tyres front and back.

Good to hear someone has had good responses with the Avons. They're a bit cheaper than my other options. All the tyres I'm looking at have an 'A' rating for the wet. In the UK we get very changeable weather, so driving in the rain is inevitable at times and I want relatively good grip and short braking distances in those circumstances. Those from the UK will know what I mean!

Cheers

Andrew

I'm not convinced by the wheels, but they are in good condition and looking around, the prices people want for Merc wheels in good condition is quite high, given what I paid for the car.

Cheers

Since you seem quite cost sensitive, I have heard good things about both Hankook and Kumho. Have also heard good things about Barum Bravuris tires in our sizes (Continental subsidiary). You talk about inclement weather. We get 55" of rain a year, mostly in June, July, and August. 20" in a weekend is not unusual (except for yankees). OTOH London gets about half that and more spread out.

Coming back from south Florida yesterday I got into three frog stranglers (visibility less than 50 yards) in 200 miles but were only about a mile each.

So my first requirement of street tires is excellent wet traction particularly when half worn. For that reason I stick with BFG/Michelin/Continental. My Jeep came with Goodyears but within 20k miles I started seeing the TC light coming on. Switched to Michelin LT2s and at 30k have yet to get a light.

Personally would rather buy a car with worn out tires and decide what to use than get one with new el cheapos the dealers like.

For some reason I just like wider tires in the rear of a RWD car, only thing to watch is do not exceed 26" tire diameter at either end.

Sounds like you know all about wet weather grip then! When it comes to cost, tyres are not something to be scrimped on, so I'm happy to pay a little more for a genuine improvement in performance. My fronts have plenty of tread, but I'd rather have a set of tyres on that I feel confident in. I'll not be doing a huge mileage, so I'm not going to have to be replacing them often. Which Contis would you recommend? The Premium Contact 6 seems to fit the bill and is actually a little cheaper than some of my other suggestions. The Michelin Primacy 4s and Pilot Sport 4 are also within my budget.

I'll whip the wheels off tomorrow and check the offsets - looking at the rim/tyre calculator I could run wider tyres on the rear, but clearance may be an issue. In terms of grip, 225s should be ample for the sort of driving I'll be doing.

Thanks again for your comments.

For Contis on a Merc I prefer the DWS06. The 225x45x17 and 245x40x17 should work on an 8" rim, 255 really needs more.

I checked and they are ET35 front and rear. Looking at the Mercedes wheel chart, 17x8s from Mercedes are 30. Does that increase the risk of clearance issues if I go for 245s on the back? It looks like Mercedes list 2 options for their 17x8 wheels if used front and rear - 225/45s all round or 225/45 front and 245/40 rear (with 30 offset).

All thoughts much appreciated.

Cheers

If you want to run through some ideas this site is good.
You can change the colour of the car to get a better idea.

Thanks for the links. Interesting to have a play... On the mytyres website they list a 17x8 with 35 offset as one of the available options, so at least my wheels aren't 'unusual' in terms of their sizing.

Cheers

Worth you hitting a local meet and chatting to members.


Although the 171 is the most populated, many started out with the 170.

@savcom @Simon cliffe


May have ideas for you.

I, and my family, have always favoured Michelins. I have got out of at least three majorly sticky situations without a scratch on my vehicle as a result of the tyres. One situation was at night (someone had 're-arranged' a barrier into a slalom course part-way round a blind corner), One was in the dry (a van suddenly breaking from 70 to a halt with no brake lights or indicators to pull into a side road!) and one was in the wet, when someone joined a roundabout in front of me and lit up their tyres trying to get out in front of me and I had to slow and steer out of his way).

I had reasonable condition Conti's on the old BMW e39 5-series when I bought it and I found wet grip questionable. Later on one Conti ended up with the sidewall cracking, so I replaced them all with Michelins and suddenly I had grip - and a noticeably quieter ride!

I have standard 16" wheels on Silkie and I had Pirelli P7s all round when I bought her. As these have a good reputation I thought I'd try these and see how I get on. I had 205/55 R16 on the front and 225/50 R16 on the rear. I've since replaced the rears with Michelin Primacy HP's and again, the ride is noticeably quieter and I think the rear grip is better (not really had to depend on the grip yet, if you know what I mean!) When the front tyres wear down I'll be replacing them with Michelins too.

Hope that helps.

Another place to look is Tyre reviews, tests and ratings - Tyre Reviews which does have some statistics you can use to help your choice. Also, if you're looking for replacing more than one tyre at a time, it's worth asking or looking for deals. I know Kwik-Fit do offers on multiple tyre replacements for example so it's worth checking your local places for deals.

You just reminded me, Martin.


I swapped out multi make for Mich on our 230.
Stuck with Mich ever since, even on the 55.


There is stickier, or better wearing, but I find Mich gives me year round use, including snow.

Looking on-line at the various tyre options I see a number of tyres come with an "XL" option, indicating reinforced tyre walls and a change from 91 to 94 rating. Are these XL options appropriate for an SLK? Is it a case of trading grip for comfort or is that an overly simplistic way of looking at it?

Cheers

Andrew

After much reading of reviews and tyre tests I decided to go with the Goodyear asymmetrics. I managed to find them at Ł70 a corner through F1 Autocentres which was over Ł10 cheaper than Blackcircles. Seemed like a good result. So I'm changing all four tyres and I've decided to go 'square' and fit 225/45s all round. Will let you know how I get on.

Thanks again for all of your input.

Best wishes

Andrew
