C70 17" tyre profile
 

Recommended tyre size, load and speed rating for the 2005 C70 is 225/45/17 93W (correct me if I'm wrong) and I'm looking to reduce the width and increase the profile of the tyres.

Are there any of you running 215/50/17 on your 850/S/V/C70's and do you have any issues with the tyre making contact with the underside of the spring seat of the front strut or rubbing to the rear arches?

Why would you want to do that?

225/45/17 W/Y has been and still is a popular size, which means, tyre choice and good prices are always to be had.

With odd/less common sizes, choices are fewer and prices are higher.

I wouldn´t go for it.

It makes no sense, 225 45 17 is a pretty cheap size for tyres.
I am running it for the summer and 205 55 16 for the winter, which is a bit cheaper.

So if you want something smaller, go for 205 55 16.

He'd need new rims to make that change - using a better tyre all year round eg Michelin Cross Climates whilst they are more expensive initially the saving on fuel and the seriously improved grip in the wet is worth having. I thought Uniroyal Rainexpert 3s were good buy the Michelins are even better.

Really? I was also thinking about buying All Season Tyres for my 17". But as I am often in the mountains for family visits I stepped away from it as I thought they won´t be good enough for my purpose. May be I should look at them again and re-think about

You guys are right...I'll just go with the correct fitment of 225/45/17 91W (to correct myself) and fit a pretty decent tyre seeing as I'm doing less than 100km per week to work and back.

I am basically looking to fit a set of Titan's (7J) for a few months, which also need to be shod, whilst I have the original Otrera (7.5J) refurbished. The Titan are originally 205/45/17 so was looking to meet somewhere in the middle. I'll most probably fit 215/45/17 to them for a little more rim protection.

I like the idea of the Michelin PS4's, as per "Your tyre of choice for your T5's" thread, but I think they're overkill for the 2.0T and the mileage I'm doing. I think I'll either go with Michelin CrossClimate, as per ASt85's recommendation, or something along the lines of Goodyear EfficientGrip Performance.

My 2.4 Torslanda has Michelin Cross climates all round - just the job for South East England - my V70 2.3 T5 was fitted with Falkens all round when I bought it - I'm not over impressed with them even in the dry - the Continental Sports on the C70 are also pants- both feels like they are skipping along the road - too hard a compound and not such great grip in the dry or wet for that matter - when the T5 gets down to 4mm on the front they will be replaced with CrossClimates - we get so little snow in Kent these days, they are the best option all round tyre I can find - in my youth I used Firestone Town and Country on the front end of an Austin 997S mini ......vibration was unbelievable but stuck like glue in the snow - braking technique was interesting - wack on the brake + tap dance aka cadence braking, let it slide and slow, then lift off the brake and steer round the obstacle..not for the faint-hearted but ABS wasn't really around in the late 60's on even the disc brake variants!

An equally good tyre.

Do you have to legally have winter tyres fitted in Germany? If you are regularly driving on mountain roads, I would think winter tyres are the best. All season tyres are OK in the UK, but we rarely get any severe weather and is the reason why we get caught out when we do.

I have 16" with winter tyres (Matador ...) and 17" Orpheus (with Michelin Primacy 4, I think)and Propus C (Achilles Sport something) both for summer. Well my Brother is living in a higher region so I have to go there some times.

The rule about the tyres is, that you have the right tyres which have to deal with the current conditions. In fact, if there is snow in the summer somewhere, in this case the right tyres would be winter tyres or All Season :confused_smile:. You can also drive with summer tyres during the winter, if there is no snow at all. But it´s the theory behind.
