Fitted With Dunlop Sport Maxx - Page 2 - Boxster/Cayman - PistonHeads UK

Strange looking Jaguar.

https://finder.porsche.com/gb/en-GB/details/porsch... Apologies for the Typo error in the Thread title ( predictive text ) but I am going to take a look at this GT4 later and I was stunned to find it fitted with Dunlop Tyres instead of the usual Michelin . I am remembering all the criticism levelled at the X150 when fitted with the Dunlop Tyres and I am wondering if perhaps I should just stop at home and take this as a sign of neglected maintenance At this mileage I would love to know how these became fitted to this GT4 ???

I never posted it on the basis its a Jaguar , I posted it on the basis it is sat on Dunlop Sport Maxx Tyres which were fitted to the Jaguar X150 as standard and received much criticism as being a crap tyre . As most will agree its mildly surprising to find them fitted to this GT4 at the mileage covered .

Presumably they did track days and screwed the original tyres?

CoolHands said: Presumably they did track days and screwed the original tyres? " Track Days " ??? Im definitely stopping at home . I seldom see Dunlop fitted to many Performance Cars nowadays as it tends to be the almost obligatory P Zero or Michelin . Clearly the technology has moved on since 2005 and the original Super Maxx but you may have it exactly right . Original tyres ruined by Track Days and a cheap set fitted to " off " the Car

The tyres in that advert have the N2 marking so are Porsche OE spec, as per the following article Dunlop made tyres for the 911 GT3. So likely to not be a "cheap" set. https://www.evo.co.uk/reviews/19830/dunlop-sport-m...

I looked farther into it and they had indeed been changed from the original Michelins .

I've got a full set of Dunlops on my X150 and have no complaints about them, seem fine to me, but I did make sure they're the Jag rated ones when I ordered them up if that makes any difference.

I have Dunlops on the rear of my XKR and will not be replacing them like for like. I've had a few instances of sudden traction loss where I wouldn't have expected it with moderate throttle.

The OE-fitment SP Sport Maxx didn't get the nickname of "Dunslips" for no reason....

Edited by reddiesel on Sunday 5th November 08:51 GT4’s came with two different tyre brands. Mine (early/mod 22 build) arrived from factory on the Dunlops, no complaints here.

My car was delivered on the same Dunlops as in the advert above. In March this year.

Commodity items aren't they here? Don't get hissy I don't mean the GT4 as well! If you wiki into Dunlop owners they probably have enough R&D background to make a premium tyre, but I'd question longevity of them compared to Pirelli/Conti.

All Porsche’s ring lap times are set on the Michelin tyres not the Dunlop/Goodyears.

I do recall some discussion/reviews about the Dunlops when they were being delivered on 991.2 GT3s andTourings. IIRC, the net conclusion was that the Dunlops were a better road tyre (quieter, more compliant, wet weather) than the Michelins, but wore more quickly on track.

Mate has them on his GT4, his one slight complaint was the slightly harsh ride and the dealer said to try the Dunlops, he was on Michelins originally, he said not only are they more compliant but the steering on them feels much nicer too, much more precise off centre. No idea on wear rate though, but to be honest, he only does 6-8k miles a year, so if he needs to swap them, or the rears, every 12 months I doubt he would be that fussed about it.

My 981 GT4 came with a nearly worn out set of Dunlop Sport Maxx that I am pretty sure must have been original. They weren't too bad in the dry, but with about 2.5 mm tread at lowest points, were really not all that clever in the cold/wet. Might not be as good as Cup 2, but if I bought a car with them on, I'd wear them out before changing them. I bet they are more than OK for dry weather and track use. They were replaced with Michelin PS Cup 2, which are also not that clever in the cold/wet. I have a spare set of 718 GT4 wheels for those, and just use them for nice weather and track days, and some Pirelli P Zero on the original rims for more normal getting about on soggy roads. Liam

I’ve since taken the Dunlops off my car. They definitely aren’t better in the wet thank Cup2’s, and borderline lethal in anything below 12C In the dry, and warm weather, they are as good, if not slightly better, than Cup2’s. But living in the north west, neither of those things happen very often. I’m on Cup2’s now.

I do now recall putting my 981 GT4 away for the winter about this time in 2018, after a hefty dose of opposite lock being needed without much warning on a cold and greasy motorway slip road (in the North West UK). “Not that clever” was probably a bit of an understatement, and Cup 2’s have never scared me anything like as much. I put it away for a few months at the time, vowing not to drive again until spring, and only with a better set of tyres. Liam

As above, these were originally fitted to a number of the GT4s from factory so nothing to worry about there - certainly not a sign of abuse

Wife's MINI Cooper Cabrio had the Dunlop Sport Maxx on when bought. These were fitted when the car was new. Recently replaced two of them with the Sport Maxx2.

Geneve said: Supplied new on my GT4 and 991.2 GT3 Touring. Not sure which generation. But, good road tyre. Probably because they are softer than Michelin Cups - evidenced by rapid wear on track - LHF was barely legal after BRDC track day at Silverstone. The UTGQ rating is 280 for the Dunlop and 240 for the Cup 2 so the Cup has a higher wear rate.

The Dunlops got hotter under load (GT4)

Checked by a tyre pyrometer? Fact is the Dunlop is a harder tyre than the Cup 2.

There are a couple of different versions. The GT4 has Race 2 which is more akin to a Cup 2 semi slick / trackday style tyre whilst you can also get a sport maxx RT which I believe is more like say a PS4S

Bu that's not important right now - as you were, back to Porsche.
