Tyres
Re: Tyres
My last set of Asymetrics on the ML lasted 10,000 miles less than the previous set, which really annoyed me. 15,000 rather than the other 2 sets which did 25,000 each.
I now have Pilot Sport 4s on it and they are a lovely tyre, lots of grip etc but it feels like the front could do with a few more psi. These are all the XL versions.
I’ve got Dunlop sportmax RT2 on the TT and I’ve been really impressed so far. The MPS4s it had on before were just too grippy and it lost its playful tucking in, it’s been a nice change.
Dave!

Re: Tyres
Sportmax RT2 worst wearing tyre I've ever had, 10k miles on an MPV that was not driven hard at all. Shame as they were great apart from that.
Re: Tyres
Can’t comment on the wear as I don’t know how long they’ve been on but I’d struggle to trust Dunlop after the amount of structural failures.NGRhodes wrote: Mon Jul 25, 2022 1:28 pm Sportmax RT2 worst wearing tyre I've ever had, 10k miles on an MPV that was not driven hard at all.

Re: Tyres
I'm keen to see him do his test now.
I'm not in the market for this type of tyre personally, but the data looked a bit mad : over 6 laps the "milder" Cup2 appear to have taken about 3 laps to get properly warm, with a starting lap 2min31, and the last two laps consistent in the 2min24 range.
Conversely the Cup2R does a 2min22 first lap, but then the times fall off a cliff. Laps 2-6 are slower than the fastest laps the less extreme Cup2 manages... with lap6 showing Cup2 a full 5.5secs faster than Cup2R
I had a quick look on autobild - with crap google translation - and there were a couple of interesting comments:
1. For the 6-lap runs "We didn't simulate a complete track day, but we still drove six laps at an 80 percent level, with all six tires at the same level". I expect their test driver is properly talented, but I'd guess it's pretty hard to drive consistently at 80% pace?
For the "hot lap" run "The more normal semi-slicks (Corsa, Cup 2 and Supersport R) are sent on the fast lap unheated at 1.7 bar. Trofeo RS, Supersport RS and Cup 2 R were previously warmed up to 85 degrees in electric blankets and at 1.85/1.90 bar (VA/HA) sent off."
So the "hot lap" times aren't really directly comparable between the two "groups".

Re: Tyres
I had the same thought on reading that. The only way I can see to do it is to start with far wider channels / sipes. Which will seriously impact dry grip….,V8Granite wrote: Wed Jul 24, 2024 11:51 pm I wonder how they will do that when being able to disperse the water is a lot down to tread depth ?
Re: Tyres
"50% of tyres are removed prematurely" but how much of that is due to replacing tyres in pairs (puncture) or replacing all 4 due to uneven wear on, say, 4WD vehicles even if a couple are still good?
I'm not convinced behind the reasoning. Most people only replace tyres when told to, usually by MOT or mechanics, usually when they're already past their best....I highly doubt the reason for this is because people are concerned about wet safety and are replacing early.

Re: Tyres
Very much that @Matty .
When mrs mik's car was last in at the dealership they sent me their usual inspection video, including tread depth checks. They reckoned the rears were measuring 1.8mm and 1.9mm and should therefore be changed immediately. And yet there was at least 1.5mm tread above the 2mm wear markers..... I got them to change them as 3mm is about the lowest I like to go, and they price-matched Camskill so that saved me a trip to my usual fitter.
The vast majority drivers simply wouldn't recognise wet weather grip signals, and have no idea that treadwear markers even exist.
The Evora is obvs lighter at the front end - when it's MPS4S got down to around 3mm you could feel how the car was struggling to clear standing water at motorway speeds. And they aren't a heavily dry-weather focussed offering. No way I was keeping them on and running them down to 1.6mm in Sunny Scotchland.....

Re: Tyres
IIRC the Audi dealer told me I needed to replace one of my tyres when it was serviced at about 16,000 miles. I changed the full set at 30k miles this week. That tyre was the lowest, but not quite illegal.

Re: Tyres
The Zoe seems quite light on its tyres. The (non-EV) Crossclimates we fitted in November 2021 still have 5mm tread left having covered about 20k.
Undoubtedly helped by the majority of those miles having been done by Mrs DJ, in eco mode, and mostly on the motorway.
