Me - BMW 440i Coupe / Dog -Cayenne
Anyone have experience of the above tyres, either good / bad.

Will soon be needing a fresh set of front rubber for the Cayenne as the original P Zero`s are down to 3mm so around summer time i am looking at replacing them.

Option one - replace the fronts with the same P Zero`s @ £720 for the pair fitted.

Option two - Replace all four tyres with the above Kumho`s @ £860 and sell the rear P Zero`s for around £150+ as they still have a decent usable 5mm+ of tread remaining.

Doing around 3k miles p/a i wont ever need to replace them whilst own the vehicle if i go for option two , if i go for option one i may need to replace the even more costly rears at some point.

For reference , 285-35-22 + 315-30-22 , and my average commute speed is < 20 mph according to the trip data.

Asking on here as the UK Cayenne forum is quite slow and Rennlist in the USA cant see past OEM rubber which are Pirelli.

Have a look at Michelin. On the GL the PS4 SUVs have lasted about twice as long as the Pirellis that were on there before :)

Seem significantly cheaper than the Pirellis that you mention too:

 
Apologies wrong size above, Google result!
 

Still looking cheaper than the Pirellis you mentioned?

For a set of F+R PS4S it will be around £1500 fitted , almost double the price of a set of Kumho`s. Yes they will be a better tyre without question but as a set for a "daily driver" are they worth the premium for 99% town driving , as a Scotsman i could go for a set of Pace tyres @ £112 each but that would be false economy , even for a Jock.

I would prefer to keep all from rubber from the same manufacturer and with similar wear , if possible due to the 4WD system.

Not sure how you quantify value for money.

Michelin cost more but they are good quality tyres and last longer.

Mine have done about twice as many miles compared to the Pirellis that were on before. Steering, braking, traction and tyre noise all seem really good so to me they’re worth the extra initial cost.

I can’t comment on the Kumhos but generally cheaper you get what you pay for.

Fitting and balancing costs will be the same no matter what you choose so something else to consider :)

Any "crabbing" issues with the Michelin`s ?

The P Zero`s are embarrassingly bad below 6 degrees , which it has been up here in Scotland since October of last year.

No crabbing issues on my car but I don’t recall that either with the Pirellis.

My personal circumstances were around £800 for Pirellis and £1k for Michelins (this was probably 2/3 years ago) but they’ve been well worth the extra £££ :thumb:
 
Had two of them on my rear inn a moment of weakness and emergency. They didnt last more than 9 months, 5000 miles

Agreed, the lack of grip on the kumho after the good year, and the lack of stability on cornering are not worth it. plus you will likely need two sets of these in a year
 
I've had Khumo tyres on a pretty fast car...no complaints , wet or dry. To be honest Id rather use pretty much any tyres than the PZero....unless you live somewhere warm they just don't get into their operating range in the UK....and when they are cold they provide far less feedback and warning of when they are going to let go than other tyres I've used. But looking at your usage I don't think you will feel much difference between tyres except road noise and comfort.
 
If I saw a Porsche for sale with Kumho tyres it would put me off to be honest.
 
Not me if its a good car otherwise....tyres can easily be changed..and lots of people...even main dealers, put cheaper tyres on when they know they will sell it soon. Expensive tyres don't add their cost to the value of a used car. Might be a haggling point...but that's all.

Khumo was crap on a rwd with 700nm torgue. I heard a lot of complaints about the Pirelli which is surprising. Goodyear Eagle F1 Asymmetric is great performance, stability and grip. I am yet to try the Michellin. I avoided it so far because when I had them on a 97hp car during summer (in a very hot country), the tyre would wrap a lot.
 
Mines was about 460 horses and just over 600nm. My much played with Mitsubishi GTO TT converted to RWD and rear wheel steering deleted......good fun to drive.....but chavvy to look at!!! Obviously it could overcome the tyres........but most cars can if driven too hard in the wrong conditions.

Dont think it would put me off it they were matching / similar wear rate and were the correct load rating for the vehicle , my CLS came from the MD as an AUC with Evergreen ?? rubber and i never had an issue with them or felt them underperforming whilst i owned the vehicle.

As with most things there has to be a sensible compromise , a set of £100 ditchfinders or "part worn" on a hefty SUV no way , a set of £500 ultra performance tyres on a "daily" 20 mph commute vehicle seems a tad overkill. I am only going to Morrisons for a pint of milk not attacking the Nürburgring corkscrew in a GT3RS.

Been looking at Continental SC6 which come in at £1250 , fitted, for the set which may be an option.

Will keep my options open as they wont be required for a few months yet plus it is due an interim oil change before then , which i will probably do myself due to me wanting to be able to sit down 😥 , something that is a bit uncomfortable doing after a visit to the main dealer.
