Hi.

For the F-type is going 265/305 in a 20 better in terms of handling and turn in or worse than the stock 255/295 assuming all other things are equal? Stock wheel. Stock suspension.

TIA

There have been some discussion on this topic so try the search. Some people have put on wider tyres for the looks but I doubt it has any noticeable effect on driving dynamics. I had the same thought but so far decided against going for slightly wider tyres.

At least theoretically, adding 1 cm of rubber width on each corner should marginally improve traction in dry conditions and marginally worsen handling and turn in through the increased weight. And when I say marginally I mean probably so little that it's not noticeable.

Hopefully someone who has more insight than me pops up and comments too.

 

Thank you!

I searched but much of this seems to be on what fits and less on what does it do.

Basically, if you moved from the stock 20" rubber sizes to 265/305 on oem sized wheels, what did you notice if anything (save a thinner wallet)? This seems like a simple thing many 20" wheel owners may contemplate (at least I am....it does look better to me...).

 

Yeah, I've been wondering about this too since I also thought that slightly wider rubbers would look even better than the OEM sizes.

Can't remember if it was here, on the UK forum or in some Facebook group but I saw at least one discussion on this topic where there were no claims of improvements and mostly pretty strong opinions against it.

 

Found this just now:

Hmm, haven't seen that one before. There was also some more recent discussion. If I recall correctly it involved an Irish member with a red 2.0 who had put on 305s.

 

You will notice no difference.

 

The SVR comes with 265/305 but I know that has some significant suspenion and traction control updates.

JLR went with 305 on the back because of the additional traction AND/OR bragging rights of saying "I've got 305s on the back." Considering they adjusted the stability control on the SVR to be more rear biased for "more" fun.... they weren't really worried about traction and was probably more focused on the bragging rights. I'm purely speculating on JLR's motivation but it makes sense given their approach in the design of this car.

To keep the rolling circumference the same, they had to go with 265. I'm not an expert but I can't see the 265 improving the handling/agility over a 255 unless the front is just not getting sufficient traction and the extra tread gives you a little extra but that doesn't seem to be an issue with this car. If anything, I would think the 265 would potentially decrease the agility. However, a 10mm difference when it's 1/25th (4% difference) is small enough that it might not be as big of a factor in agility and traction but when you compound that with the tire weight increase, a 1-2 lbs difference is a 5-10% change and now it's a bigger factor when combined. To offset that, JLR went with a much lighter wheel on the SVR.

I currently have a set of 19" with 245/275 but will be going to a set of 20" with 265/305. I see you live in the mid-Atlantic, if you're within a few hours of VA, let me know and you're more than welcome to take my car for a drive.

 

How big of a difference in the ride do you have with the 18" wheels vs. 20"? Last F-Type had 18" and the ride was OK. Looking at one with 20" wheels and I'm thinking it's going to be a much harder ride then with the 18". Thank You.

 

I did forged 20" OEM carbon wheels.

Added Conti DWS06plus tires in 265 front and 305 rear in the proper sidewalls. No issues. Love it.

Car handles better. I noticed only better....forged wheels even though larger are slightly ligher than the cast 19's (and are much stronger). And I can get just one replaced in a day or two max.....so for me super right choice.

Thank you everyone.

 

Night and day difference to me. I went from a base 2018 to the base 2022--18" wheels with Continentals to 20" wheels with Pirellis--and the ride in the new one is much stiffer and sports carish (is that a word?) As my experience is just over 2 weeks and 200 miles with the new model, I'll withhold a decision on downsizing wheel diameters until a later date. Not engaging dynamic mode does moderate the ride a tiny bit, but it's definitely totally different from the 2018.
Just my two cents.

 

Thank you for responding. That is exactly my concern and, I think, I actually drove one with 20" wheels before I bought my 2016 and when I drove the 2016 (18" wheels) I thought it felt much better. Still a kidney and back buster (I'm old) but better. When the tire on the 2016 wore out, I switched to a different tire type and that made a difference. Need the higher sidewall. I'm going to speak with a couple of tire people and see if there are certain 20" tire that will smooth it out after I burn up the ones that come with the car. That's assuming I get the car but it looks like everything I'm seeing has 20" wheels. Even with the 18 wheels, we went on a 5 hour trip with the car and it nearly crippled me. OK, I'm a little dramatic. That's the problem. Want a hot looking sportscar with a minivan ride

 

Getting quality tires will improve the ride quality regardless of wheel size. A new soft compound Performance All Season Michelins or Continentals both ride better than many of the other brands out there. 18's will have taller sidewalls than 20's if the tire diameters remain constant and therefore are a little more forgiving when hitting potholes, etc. but will generally not corner as well for the same reason. As far as widths go, there is a reason that all of the "supercars" or high performance cars fit the widest tire that will fit properly. The actual benefits far outweigh any theoretical negatives when it comes to actual performance on the road and track. Yes the steering effort might increase slightly, but you will have more grip in any situation both laterally and in straight-line traction.

 

Update: I found the solution for me and there will be no downsizing of wheels.
Entered Configurable Dynamics and for My Setup selected Comfort setting for the suspension. Done.
Then I can toggle to and from Factory Setup and My Setup when conditions (or the spirit) moves me.

 

I find the ride more to my liking in the 20" wheels (factory forged) with 265/305 continental dws06 plus tires. The tires are amazing in that the lateral stiffness is all there but they don't ride harsh like i had in the M brand as 3+'s. Your mileage may vary....but I like the added sportiness over the prior 19" wheels with the same model tire (different, albeit OEM, size).


Agree with sassysarah....even with the 20" wheels if I run in comfort mode it is pretty nice....coming from a car with ohlin road and track coilovers.....set to about midway. Jaguar does a great job tuning the susponsion for GT, sort of sport....this is not set up as a track car and I am ok with that because my commute is not on a closed circuit.

 

I just don't like the look of smaller wheels on the F Type!

 

the only difference you will feel is in your wallet/bank account when its time to replace the rear tires, prices between 295 and 305 tires is around $200+ difference

 

Yep...worth it to me.

 

Are spacers to make the OEM tires appear wider even on the radar for you? I’ve seen at least one owner who installed them and liked the outcome.

 

Yes I have 305 rears and 265 fronts on stock 20”, there’s no difference in ride or grip really than OEM size, although you can see visible difference,car is also lowered and 15mm spacers all round, hoping upgrade to 21” soon, as per photoshop on last pic
