What size of PSP 4 s and load rating did you fit ?
I couldn’t find any in 19;@ 275 /40;/ 19:.but that my be a local supply problem ?

Also the 105 Y is important as is the tyre pressures.
Some car tyre set ups are very sensitive to any pressure variation, others not so .
Theses Bentley GT continentals I find are the former .

I just wonder why the factory ( and it’s pretty extensive R +D facilities) choose the collaborative with a manufacturer like Pirelli ......and end up coaxing the manufacturer to make a specific tyre adding the symbol B1 for Bentley .
There are other manufacturers that do it too eg Porsche use N etc etc + many others .

On the other hand some don’t ( more regular family boxes ) and just spec rating and size , leaving it up the owner a more carte blanch decision .

currently I alternate depending on the season between OEM Pirellis and Dunlop’s winter sports both same size and 105 Y .
Ride are fine ........just watch the pressures l

 

Size/rating as follows

275-40-ZR19
XL and 105Y

readily available in the US, so I suspect a local supply issue.

Great .
The Mich PSp 2 do get rave reviews for sticky ness on just about every performance car oriented switch .
I have a 70 ,s carbed Ferrari on Yokohama’s for summer fun on the twisty bits .So tend just to waft about in the Bentley.I don’t see it as a sports car imho .

How ever having said that the C GT is a formidable hill / pass climbing machine , despite its mass .
I had a tussle with a Porsche C4S and he can’t keep it glued my bumper ( going up alpine passes with multiple hairpins ) .
I seem to brake earlier , so he closes up but crucially i can get on the power earlier just before or on the apex and open up a couple of meters before the straights .On the straights in sports mode I pull further away .
He catches me in the braking zone before the next hairpins .Thats on Pirelli P zeros B rated .

The other thing is I seem to wear out the fronts twice as quick as the rears so never get to a position of all 4 ready for a change .
So seem to buy them in pairs and put the fresh on the fronts .
Tyre fitter who changes them over to winters chalk marks them and replaces them exactly as they come off inc exactly the same wheel at each corner .

 

The weight of the GT is a killer and it certainly isn't a sports car by any means, lol! It's a heavy luxo-cope (on a modified sedan chassis) with awd and a big motor. (save the awd, a bit 70s American muscle car like, albeit certainly a lot more refined in the area of creature comforts)

I think though the ps4s heavy aramid sidewalls help a lot in that regard (weight) due to their sidewall stiffness, dual material inner/outer treads and I suspect as a result, very, very low slip angles. Weight wise, they also seem to weigh more than their competitors by several pounds each. Long sweepers on the highway are much less ambiguous, off ramps a fair bit more fun too. Much of the handling is the shocks, and the stiff setting and trans sports mode helps a bit (by holding revs in sweepers), but I find the tires also add another improvement in a bit less 'floatiness' and sure footedness.

One downside is I won't be able to use these in the very cold winter as, apparently, the rapid temp cycling causes some type of accelerated degradation, due to the compounds used.

I found that the inner front tires wear much faster than the outers, and the front's more than the rears, for sure.

The early cars, like mine, seem to plow a bit in the front end too (understeer). Indeed, a proper, lightweight, balanced and properly sorted sport's car is in order for the more spirited driving. For that I went with the PS Cup 2s, since they are not likely to see inclement weather.

When I participated in PCA time trials in the 90s, used to spend a good amount of time corner balancing weight/shocks on scales and had Yokahama A008Ps heat treated, shaved and siped for extra grip and mounted on magnesium rims with mag lugs, etc. Everything to reduce unsprung weight, body roll, slip angles and improve cornering g's. Lots of negative camber was a common tactic at the time, depending on the track, along with electric heated covers to keep the tires hot and ready.

 

ps, I find turbocharged cars are almost always good hill climbers, as the added load spins them up at much lower revs.

 

Hey TeamJones,

Thanks for asking, Looks like mine might be in my possession by 11/22 or so.

How did your speed bumper turn out? Would love to see some pictures!

 

Should have it soon...turns out I needed a few small items and I was having a tug a war with myself on getting the last two items, the side light at the bottom of the bumper and the chrome piece. Light was $170+ and the chrome piece was $140+. On eBay it was even more!!! So they should be here today and I should be god by the middle of next week.
