After driving, right front is warmer than left?

Interesting issue; what about the tire pressures are they correct and equal side to side? The front wheel settings (alignment) do seem to make some difference but certainly a puzzle!

 

I would have them check the alignment- your alignment could be out and you still might not feel the car pulling. Is there extra wear on any of the tires? It could even be a rear alignment issue- so it should a full alignment - not just front.

 

Ditto as post #4. Definitely check on the alignment and see if there are any tire wear difference. You might also want to check the psi and actual temperature with a pyrometer to confirm the difference.

 

I don’t know if this will help any, but thought it worth throwing out there.

Measure the circumference of each tire when they are both aired to the exact same pressure. I have seen in turf equipment tires, that two tires of the same size, even coming from the same mold, thru mold wear, can vary in circumference, or height. Different height tires can cause a belt driven mower to track to one side. the taller being formed in a worn mold, the shorter in a fresher mold. The solution in the turf industry is to air them so that they equal in circumference or diameter, as opposed to pressure.

I understand that vehicle tires are likely going to more precise, but there may be something in here to help in your diagnosis.

 

Might this have something to do with the radiator layout?
In some cars the hydraulic steering radiator is on the right side near the front wheel well.

 

Camber on the road means slightly more pressure on one side creating friction heat which increases pressure. Go round a roundabout for about six laps quite quickly and you will notice the loaded tyres are much hotter than the inside tyres. Going straight you find often the offside tyre is hotter and 1 or 2 psi higher. stop for half an hour and they are then the same.

 

It could be any of those. You could also find a race shop that might be willing to spend some time with you on this or you could try taking readings after driving using a pyrometer. See the temps at the surface of each tire...

I have heard about the use of pyrometer to determine proper tire pressure. How can I determine what is the proper temperature? I am sure there are many variables that determine that, ie ambient temperature...what are those variables?

 

You could take measurements across the area of the one tire that is not in question, then take the measurements of the one that is in question, and look for discrepancies.

 

I think that would be interesting, but I'm not sure if it will be anywhere near as accurate. I think you are looking for more than 1-2psi differences.

 

Either the Pirelli has been overheating, or maybe the process of changing the tires reset the TPMS in a way to make it normal again.

 

Stop only turning left and loading the front right.

Only joking. The Pzero are not great, I know a small number disagree, but here in the UK they just don’t work as it’s not often warm enough. I took brand new Pzero off mine and changed to Michelin PS4s. I just don’t want the enjoyment compromised by the wrong rubber. Which curiously is what my wife said......
