I do remember one member posting on here that they got given BZs but can't remember if they were mixed in left to right or front rear. Seem to recall that they had to have them changed because it was a big problem.

If the post at the top is correct then you should of had MZs if that is what you ordered. Get them swapped if you can.

 

The Bridgestone advice seems to be correct. I have just had new 17 in fronts and the tyre does not seem to carry the supplimentary MZ or BZ or CZ marking - it just says RE050.

Frankly there is some real tripe posted on here about tyres for this car. Any well known brand of tyre of the correct size will work. It will have different grip charicteristics in different circumstances as all tyres do, whatever car they are fitted to.
A lot of people have a favorite brand and stick to it, a lot don't like mixing different brands front and rear.
At normal legal speeds in the UK it makes little difference IMHO. On the other hand if you insist on driving as if you are a racing god on the public roads then perhaps it does. However real racers do it on the track.

 

I'm sure the MZ, BZ or as on my fronts it says GZ are just the compound material of the rubber. The RE050 is the actual tire tread pattern.
I've got MZ's on the rear and GZ's on the front.

 

Theres a lot more to it than just compound material, but as you mention RE050 is the tread pattern.

The spec can mean anything from a slightly different kerb rib to a very different internal construction, sidewall hardness etc.

Go with what Bridgestone says at the top of this post if you can.

As I have mentioned a few times on here you can end up with completely incorrect tyres on your S2000 if you just specify size and tread pattern to the dealer. People I know have had MO Extended tyres put on (the wrong way round as well) and you can get yourself in a lot of problems if you dont check.

 

BZ's sitting slightly higher compared to the MZ's and that was the issue, one of our fellow members had. ( 15mm difference if I recall, between the BZ and MZ tyre)

 

This might help if you decide to use a different spec of RE050. Its a little old but Bridgestone UK dont like giving the latest version out as it contains new specs and fitments not on general sale.

Rears:
BZ are Merc Fitment
TZ are Merc MO Extended (avoid like the plague)
GZ are Subaru if i remember correctly.

 

That might sound correct but it is not!

The last time I looked, the thread pattern was different on MZ's than any other RE050 for some strange reason, so it is more than just the rubber compound for the MZ Honda fitment.

 

You are joking right? That or you haven't experienced many tire combinations on the S or any other performance car.

Tires are everything my friend, whether for the street or track, since it is the only part of the car that has contact with the road. They effect braking, corning and everything else about the cars characteristics, in fact even average drivers can notice a difference. I wouldn't have gone to the trouble to import RE01R's from Japan for my car if there was a noticable improvement.

 

(except for your spelling of tyres).

If you think tyres don't make a difference at legal speeds, then there's probably not a lot of point having a sports car, because after all having a sports car doesn't make a difference either. Just sell up and let somebody who'll appreciate it have your S.

 

Er, think thats what i said!

RE050 is the tread pattern, although there may be some small changes depending on spec and if there is an A in the spec (RE050 ACZ for example). Spec can mean changes to most parts of the tyre but generally tread pattern is very similar.

EDIT: I should mention that the spec can have a large difference on the price per tyre as well. Which is why its always worth checking you are getting the correct spec if you are quoted a pretty cheap price.
