Turbo-G Posted October 30, 2012 Share Posted October 30, 2012 Hi all, Looking to purchase 4 OEM Bridgestone Potenza RE050a tyres in 225/45/18 and 245/45/18 Looking at numerous tyres sellers, I'm confused which compound to go for as I seem to be seeing conflicting information. Presumably the rears should have a load rating of 96W and the fronts 91W? What's the difference between RZ, JZ, Z, BZ, EZ and DZ? If someone could advise what I should be ordering as per OEM recommendation, that would be appreciated. Thanks! Quote Link to comment Share on other sites More sharing options...

stanski Posted October 30, 2012 Share Posted October 30, 2012 Ditch the Bridgestones and buy Falkens instead - they transformed the car for me much better feel. Quote Link to comment Share on other sites More sharing options...
NeilMH Posted October 30, 2012 Share Posted October 30, 2012 The one to go for is DZ Quote Link to comment Share on other sites More sharing options...
Ebized Posted October 30, 2012 Share Posted October 30, 2012 The handbook says for the tyre sizes you are quoting and on 18" wheels, 91W for front tyres and 96W for the rear tyres. The letter/number is explained here: http://www.blackcircles.com/general/speedrating So as long as you do not go below those numbers or letters you will be fine - in fact you may find 'Y' rating tyres at better prices Quote Link to comment Share on other sites More sharing options...

DB Dan has bit of a downer on the 452 Falkens, whereas a lot of us who have used them over a long period found them excellent value for money and for everyday road use are a perfectly competent tyre in the wet and dry. But bear in mind Falken now have the 453 out as a replacement and we do not know the feedback on those yet. Quote Link to comment Share on other sites More sharing options...

It was slightly tongue in cheek I'm perfectly prepared to believe the FKs are fine for everyday driving. That said; whilst I'm not going to diss a tyre I've never used, I'm also not so sure I'd suggest 'ditching' tyres that Ferrari saw fit to put on the Enzo and replacing them with semi-budgets with an at best mixed reputation.

AK350Z Posted October 30, 2012 Share Posted October 30, 2012 Think these were the ones I got last time from Canskill: http://www.camskill.co.uk/m61b0s315p52216/Bridgestone_Tyres_Car_Bridgestone_RE050A_Potenza_Bridgestone_RE_050_A_-_245_45R18_96W_%28DZ%29_TL_ Quote Link to comment Share on other sites More sharing options...
Turbo-G Posted October 30, 2012 Author Share Posted October 30, 2012 Thanks for the link. It would seem that KZ is Nissan approved, whereas DZ is Toyota/Honda/Mazda approved. Quote Link to comment Share on other sites More sharing options...
Turbo-G Posted October 30, 2012 Author Share Posted October 30, 2012 Just spoke to the chap at Event tyres, and he told me there would be no difference in compound between a KZ or a DZ for example. The only difference being the price. He told me that dependent on the manufacturer in which the specific 2 char code is applied, the price may vary. Often more prestigious manufacturer 'versions' will cost more even though in principle they're the same tyre! Manufacturers use those 2 char codes for their OEM tyres from new. Makes sense, but is that correct? Quote Link to comment Share on other sites More sharing options...
