I'm ready to bin my Continentals that came on my 2017 F-Type Base Coupe on 18" wheels because I don't like the tires, not because they're worn out. I am requesting wise advice and sage council (why am I posting here ;'-)))) about tires. I want to stay with my original 18" wheels. I wouldn't mind if the ride was better or quieter, and would like to fill out the wheel wells better. I do like grip, especially in the rear (planning on getting a tune). I do more drag racing than canyon carving, but do both with enthusiasm ;-)). Of course, 95 miles out of 100 are spent in city traffic. Rarely driven in the wet.

I wouldn't mind meatier tires, but TireRack tells me that there is no +0 option for my car.

Michelin's web site informed me that they didn't have a recommended tire for my car because the available tires couldn't handle that much weight. HUH??? It seems that PSS are available in the stock size, but not PS4S. Is that true?

I wouldn't mind if the tires filled up the wheel wells more. Using stock tires, what size of spacers would be appropriate (some of the roads I drive are not great)?

Thanks to all who bother to reply, certified geniuses and ******* alike, and I hope I can tell the difference ;-))))))))))))))))))

 

PS4 are available. I have a set waiting to be installed.

 

Sorry, just realized you have 18" wheels

 

 

245/45/18 on the front, 275/40/18 on the rear.

 

What is the load rating for each size? THAT may be the reason for Michelin's reluctance if their offerings don't match.

+++++++

That said, I mistakenly fitted a one-size lower load-capacity tire to our daily driver SUV. I noticed a decrease in steering response unless I increased tire pressure by 3 PSI. No issues, however, running that car like that.

 

MSS are a bit dodgy in heavy rain, so if you get caught in a flush floods that happen in San Antonio you shouldn't drive through it. M4S wet handling is one of the key areas where tire improved over MSS. I'd say consider getting 19 rims.

 

Now who would have thought that we are to a point where 18" wheels could be considered insufficient. Not too long ago they were a dream only achieved by a select few.

 

I want to stay with 18" wheels.
Larger wheels seem to have a rougher ride and a higher possibility of wheel damage. I don't need the last tenth of a percent of a G worth of grip. Also, there's my cheap (oh, did I say that out loud?) SWMBO to consider...

On the Michelin ratings - the fronts are XL rated, for 1764 pounds per tire. The rears are 99Y rated, for 1709 per tire. Now I know the F-Type is a little porky, but mine weighs a lot less than 6946 pounds, even with me and fuel.

Also, I'm retired and don't have to drive in the wet.

 

I'm with you on two counts: Retired and unwilling to ride on 19" or 20" tires, or larger because of the rough ride. Before I ordered my 2013 XF I test drove cars with 18", 19", and 20" wheels and frankly would not have owned the two with large rims. Maybe I was spoiled with my XJ6 and XJ8, or maybe it's just old age...it is what it is.
Hopefully by the time I need tires Michelin will be offering the preferred ones in 18".

 

I just went through this dilemma... PSS are available in our size but rear load rating doesn't comply with oem requirement., PS4S arent available for the rears.. I went with Nitto 555G2's waiting to get them installed next week.

 

With my '19's 4S had less choices, I did go wider in back but not as much as I thought I could. Many more options for '20's.

 

It's Ian Callum's way of telling you that Jaguars need BIG wheels.

 

I'll say. The worst part of the I PACE is the ridiculous 22s. The rest of the car looks pretty good.

 

Yep, wheels make all the difference.

Could you elaborate please? I'm thinking about doing it anyway... but want to know what I'm getting into.

 

The oem load rating for the rear tires is 103 (1,929 lbs) and the Michelin Pilot Super Sport has a rating of 97 (1,610 lbs), that's 318 lbs lower per rear tire than it should be.

Think about the load that placed on the tire during acceleration or cornering, its a substantial difference and I wouldn't take that risk!

I did a bit of research and found the Nittos to have some great reviews and match the PSS in performance.

Thanks! I don't want to have a scurdy jag...

 

Nobody likes a scurdy Jag!

I just got word from my attorney that JLR approved my lemon buy back so I called and canceled the tire order.

If you do decide to go with the Nittos please let us know how you like them, I know two other owners with the stock 18s that are curious.

 

I'm thinking that I may just stay with the Conti's - they aren't worn out, just a little scurdy - until a better option presents itself. Maybe Michelin will make PS4s for my rear in the right load range... Oh well, my wife will be happy - she wants me to wear them out to the cord.
