Wheels Lightweight/Track Summer Wheels & Tires

To be honest, a light rim with 235/45 or 245/40 R17 won‘t be the worst option for track use or for winter. I think there are plenty of wheels which can clear the 245mm brake. You won‘t win a show and shine contest but technically spoken....not bad. ;)

Caliper to inside wheel is to close and well below the recommended 3-4 mm clearance. This recommended clearance takes in consideration, wheel flex, heat expansion and debris that can get logged between the wheel and caliper.

Like I said, it not something to consider or do, as it's not a recommended alternate size for the Veloster N by any wheel manufacturer or distributor and for good reason. Just because something can be done, doesn't mean it's correct or safe.:)
 
Fascinating how big the difference is between the "normal" PS4S and the PS4S in DT1 spec. You can really see the difference of 0,3" in tread width.
In Germany the only available is the DT1, shown on the left side of the table:

Here's my DT1 PS4S:

Thank you for sharing this very interesting information! 👍
I went for exactly the same wheel-tyre combination like you have but in the colour 'Light Grey'.
I didn´t find any precise information about the DT1 specification of the Pilot Sport 4S.
Looks like we made a bad deal compared to the normal 4S version; the DT1 tread is less wide and less deep. 😅
Do you perhaps know something about the rubber compound? There has to be a good reason for the production of the 'DT1' specification.
I can´t wait to test the car on excellent 18" Michelin tyres in daily driving conditions and on the Nordschleife.
 
No, haven‘t any information about compounds. But the different „size“ of the DT1s are the reason why this spec has to be mounted axle-wise and not to mix with the normal ones.
They are working great in Hockenheim, I’m convinced they will also do proper on the Nordschleife! Don‘t start them cold below 2,1bar, the sidewalls are not the stiffest. Warm them slowly, don’t overload them till about Adenauer Forst. Warm pressure of 2,5-2,6bar should be perfect.

Widest I would go would be 8.5 and Dia 18 , go with the lightest possible. I will have 2 sets one at 7.5x18 with 225 and another set at 8.5x18 with 235. Offsett as close to 55 so 45 to 50 is good. I hope this helps
Be careful with caliper clearance. because they have a sliding caliper when you renew brake pads the caliper will slide out slightly further and could cause a problem.

Just completed installing my new Oz Racing Ultraleggera 18x8 rims with Michelin Pilot Sport 4 (235/40/18). Cleaned the brake calipers at the same time.

Driving feel is just great. A little more comfort over uneven surfaces compared to 19 inches.

Total weight pr wheel is 19kg.

Here are a few quick cell phone snaps of the car:

Look good , do they clear face of caliper okay ? what offset ?
 
I once took some measurements regarding 17" wheels. The inner diameter of the barrel should be ~400mm to clear calipers on a Performance pack. But keep in mind the front/back sliding motion and brakepad thickness like mentioned here before.

Hi all!
Who uses 245mm Tires? Can I get some Pictures, Wheel Info (Size, Model, Weight, price?) and your experience?
 
If it will be helpful to someone - my 17" rims have a clearance of about 7-9mm with 330mm front brake discs (not PP).
 
Hi all,

I'm about to buy a set of Bronze BBS CI'R's. Size 19x8,5 ET43. Will they rub with the OEM Pirelli P Zero's (235/35/19)?

They look so good on the car (atleast on the configurators).

Thanks in advance :)
 
Hi guys, finally I got the ultralight rims - Rays Volk Racing CE28NF)! As far as i could find information, these JDM rims were manufacturing in early 2000s. My set has a perfect geometry and a little cosmetic damage outside surface on a pair of rims. So, overall it is very well condition for approximately 15 years old rims. Especially, I am happy that the rims have 50mm offset and I absolutely sure it is much better than the most popular 45mm offset. And last one, I know guys, you are all have money for rich and shiny OZ rims or ultralight magnum rims, but I paid for this set 520 Euro (130 Euro per rim). Also, I'm a little surprised, there is almost no mention of these rims before..

Those are some Legendary wheels from back in the F&F age! Every wheel made of Japanesium is a good wheel, asspecially if it is a forged one like the CE28. They did cost an arm and 3 extra fingers back in the day so finding a good set now can be a real bargain.
There are a ton of forged japanese wheels out there, but they are more popular in the JDM scene, hence the
ignorance on this forum. We are lucky with the asian bolt pattern of 5x114.3 which unlocks a ton of JDM wheels 😍

I made a question regarding the DT1 spec in the Pirelli P Zero thread and was speculating that it may have improved rim protection compared to the old variant. Especially the DT1 FSL (which might be the same as just "DT1). Any thoughts on this? 😅

I also noticed that it has different EU fuel efficiency rating. The regular version has rating of "C" versus DT1 which has rating of "D". So worse fuel rating which could hint at slightly more sticky compound which has more grip but also higher rolling resistance? Or it could be just the new 2021 EU labeling standard which gives it a different score. 🤨 Although I can't find any word about that changing the scoring. 🥵
