Yeah, we are going to beat this poor horse to death

Have a '17 R with 9k+/- on the clock. The rear tires are toast. I live in the Mid West (USA) So,.................

1 - replace rears with new Pirelli's - keep fronts the same (which could go for another 3/4K)

2 - replace all 4 with new Pirelli's

3 - replace all 4 with Toyo's

4 - replace (4) with all season (yes, I read the thread that Pirelli does not want them driven in less than 50 degree temps)

5 - have two sets - summer and winter

6 - replace with different brand - better than Toyo or Pirelli

7 - ditch the F Type and buy a Tank

All suggestions are welcome! THANK YOU

Dump the Pirellis and get Michelins.

If you really want all seasons go with the Continentals that RickyJay uses. He drives in all weather in Maine with those and he has no problem leading at speed the rest of the year!!

 

 

There are many threads already on much the same subject, here are the two most recent ones:

https://www.jaguarforums.com/forum/f...wheels-189454/

 

The horse's last word was ... M.I.C.H.E.L.I.N

 

As others have suggested there are probably more recommendations for Michelin P4S and similarly many critics of Pirelli P zero on F Type in general and particularly with F Type R RWD

All summer tyres are much less suitable and not designed to be operated at temperature below 7°C

 

I also live in the Midwest and I found myself in the same situation. I ditched the Pirelli's and went with all season Michelin's (Pilot Sport A/S 3+). I highly recommend them. Night and day compared to the awful Pirelli's.

 

Just go for it!

 

It is winter here so I am seeing temperatures of 0 deg C on the way to work in the mornings and I am not noticing any great drop off in performance with my new Michelin P4S's.

 

Same here in South Oz.
Two or three nights a week I park in SWMBO's driveway and when I get in the car early the next morning it is usually between 0C and 4C and the poor little car is covered in frost, and there is very little noticeable drop in tyre grip. However I take it easy for the first few kilometres with little or no WOT action.

 

Never new it could be that cold in Oz.. Are you up in some mountain range ?

 

I also ditched the Pirelli and moved to the Michelin PSS (pss now replaced with a newer designation)..and went to 305's on the rear. I preferred the summer tire for the summer due to handling feel and so had a set of Coventry wheels that fit Jaguar and Toyo snows (walnut shell technology).. lots of snow here and ice, for winter driving. (Overall the Michelins are far better than the Pirelli.)

The summers are the 20" and the Coventry are 19" with a slightly taller sidewall so overall size is equal. These 19" should just fit over the front brakes as they did on my XKR and I was told the F V8 front brakes are the same, if not ceramic. Anyway, I'm not sure of your winter conditions but I can say for sure the summers are like being on skate boards once we get below freezing.

If we did not have snow or ice the all season would be an option as they are ok below freezing, but do not handle as well as the Summers, in my experience.

Actually in the end I moved the F to Florida and plated it their for the winter, so never put the snows on it, and now use the snows for my XE sport. Usually bring the F back to Canada in the summer.

Nup, down on the plains just north of Adelaide, but SWMBOs place is halfway up the foothills of the Adelaide Hills (although still well and truly in the 'burbs).
And it's only a few mornings in the year it gets down to 4C or lower, I have never seen a negative temp in my life and I have never seen snow in Adelaide although I have been here for 60+ years.
Remember we are talking Centigrade and 0C = 32F.

 

@OzXFR.

Adelaide has a pretty pleasant climate then. I once had a professor in Delft University who worked in Adelaide also,
switching every few months, I think he was geologist, its almost 40 years ago now.

 

2017 R. OK - ready to ditch the Pirelli's for the Michelin P4S. I think I've read that you can go from 295 to 305 on the rear without any mod.
1. Is that correct and the right move or stay with the OEM tire specs.
2. Does anyone have a opinon on performance going to the 305's.
2. If I do 305's on the rear what is the recommended specs for the front.

Sorry in advance if the above has been answered before.

 

1. Thing is that for legal reasons the circumference of the thread has to remain equal with OEM. A big change in circumference changes the reading of your spedomoter.
There are plenty calculator tools for that on the web. I think maybe some edge might rub to the arch or inside the car. Though someone said designers take some space for snowchains inconsideration. You might get away with it;
2. It has to do with how much power your car has. I have the 4-cylinder 300HP. As far as I know, same tires as V6 cars [ 340/380HP ]. The V8 would need bigger shoes ,
or they just control it with traction control, electronicly, not mechanicly like
3. Rough estimate : 295+10=305 , so 245+10= 255 ...

But I DO NOT KNOW if it will fit ; like steering. Would you toucht the tire somewhere under the wheelarch...

But my idea is : don't do it. This affects everything, from car stability at high speed to the vectoring function controling your car .. Its not like an old ponycar with everything basic..

 

Thanks Dan - exactly yhte advice I was seeking. What I hear is - if it ain't broke....... so the MPS4S it is. Cheers

 

If you have OEM 295s on the rear then you have 255s on the front. If you don't have adapters or spacers on the car, you can safely go up 10mm both front and back. Some of us have upsized the rear only and others have upsized the front as well.

Here are actual diameters:
255/35-20 27.0" (OEM)
295/30-20 27.0" (OEM)

265/35-20 27.3"
305/30-20 27.2"

245/40-19 26.7" (OEM)
285/35-19 26.9" (OEM)

Upsizing by 10mm only increases the diameter by 1.1%. The speedometer will still read higher than actual. You will note that the 19" OEM tire size is a smaller diameter than the 20" tires by that same margin. No laws concerning tire size in the U.S. other than they cannot stick out beyond the fender. I can't wax poetic on handling improvement as I had upsized when I transitioned from the Pirellis. (stepwise improvement in handling).

 

I have 'factory fitted' :
245/40-19
275/35-19
