Inner tire temps 10-15 hotter than the outside temps

So Im trying to fine tune my Icon Camaro and Im down to a 8:33 with a second or two left on the track.  That said, I checked my tire temps and im showing about 10-15 deg difference between inner and outer temps (inner is hotter) on all four wheels

Here are some of the settings

Camber Front    -1.1
Camber Rear    -1.0

Toe Front      0.0
Toe Rear     -0.3

Caster      6.2

PSI is at 32 lbs after my hot lap. (started at 28.5)

Suggestions?

Thanks

Just remember grim that the inner temps should be warmer most of the time. During corners it's OK if the outside goes a few degrees above the inside, but everywhere else the inside will be warmer.

 

Also, the "stiffer" the car is the less negative camber it requires. This is something that Forza tuning has in common with real life tuning.

-1 is a good starting point for camber and if that is too much negative I'll soften the car up so it rolls more. My setup on the Escort currently has -1.1 and the temps are perfect IMO.

Good to know. I stiffened up the arb's on the Camaro for the ring and just happened to look at tire temps. Inners are still warmer but much closer now. That would explain why the temps went up. I adjusted them to -0.8 and -0.7. Thanks

Yeah, a little difference is ok. I think as a general rule, If you've got more than 10 degrees difference between inner & outer temps, then you may have a little too much.

Thanks. I'm down to a best time of 8:31.5 clean and a normal time around 8:33. Car is right on the edge for me and I think if I free it up anymore the mistakes will be amplified.

I personally don't pay much attention to temps. I peay more attention to pressure when the tires are warm.I shoot for 34 LBS when hot.
