Just noticed my zed has one Bridgestone RF and one Bridgestone non runflat on the front wheels - found this noted as an advisory on current MOT - obviously still passed but is this legal ? Am going to replace them anyway but don't like to think its illegal or unsafe!
 
If the MOT was awarded probably not illegal .......but I certainly wouldn't want to drive that set up
 
With that set up, its hard to know what the car would do under stress, e.g. emergency stop, evasive manoeuver in traffice, hard cornering etc...

Probably safer to have all non run flats, or all run-flat :thumbsup:
 
Used online Tyreshopper - stayed with runflats as I have two new runflats on the rear wheels ( put on by the dealer when I bought the car. Went down to National Tyres ( who Tyreshopper use to fit ) to check that I was ordering right size - and yes he did say they shouldn't have passed the MOT as the set up between rf's and non rf's is netirely different - he also said they are not allowed to fit non runflats on to cars that are set up for runflats ( I know this may not be true but he wasn't being awkward just doing his job and I wanted RF's anyway). Upshot was I went home and ordered on line ( allegedly saving over £70 ) - he phoned me within an hour and said he could fit them this afternoon which he did - got the wheels tracked ( aligned ) as well - he said everything went well ( apparently with the zed the tracking thingees usually are seized up )
Went with Continental Contacts to match the rears - total cost £318 including tracking etc - have to say the car feels better. AND not a mark to any of my alloys - would highly recommend Tyreshopper for their service.
 
He's bullshitting you in saying that he cannot fit non runflats to cars designed for runflats,but, that may be what he's been told.Any one can fit non runflats, its your choice as a consumer as to what you fit.It may not be recommended, but that's only because they are harder to fit on runflat rims. Runflats have only been adopted by car manufacturers because rims are getting so wide that spare rims are impractical and they didn't want to go the spacesaver route.No spacesaver saves the manufacturer cash and weight in the car,so they can package the car differently.It's not really a safety issue IMO,just the packaging of the cars.Fit whatever you want, it's what most of us on this forum have done/are doing.

I don't think he was saying that he couldn't fit nonflats , more that as you say its not recommended - after what the majority say on here if I didn't already have two new rear runflats I would have considered going all nons but that would give me all the hassle of selling the old ones ( assuming they wouldn't be damaged taking them off ) telling the insurance company etc. TBH I would probably stick to Rf's in the end because I like originality and living here on the IOW there is only one dual carriageway that is barely 1/2 mile long where you can legally go 70mph , the rest are max 60mph. Makes you wonder why I have a car that can do 155mph - who cares - I don't - just love this car!!!!!!!!!!!!1
 
A lot of places have made it 'policy' to refuse to fit non-RFTs to rims / cars that are designed to use RFTs. Kwik Fit, National Tyres and a bunch of others I tried. There's always someone who will do it though, and as said it's not a legal or safety issue from a consumer perspective... Though I guess if the manufacturer says RFTs but a company fits non-RFTs, and then there's an accident, then there could be a legal case in there that the tyre fitter would rather avoid the possibility of. Arse covering is so common place on a corporate level... However it can be solved with good old fashioned cash as I found out when I had an RFT repaired recently. Needless to say I didn't get a receipt...
 
A RFT and non-RFT on the same 'axle' is an accident looking for a place to happen! On a grocery getter, you could maybe get by with a RFT pair on one 'axle' and non-RFT the other, but why? On a performance car, it's still a bad idea, but not as extreme as on the same axle.

Most of us here love to hate RFTs. The OEM ones were pretty bad. These days though, there are several RFTs available the are perfectly good. Tire technology continues to advance, while some people's opinions are stuck in the past!
