New Tyres on Front or Rear?
So have a evening session at Brands, I have 2 pairs of 595rs. One pair has 1mm above marker and the other pair has 2mm. Am I right in thinking I should put the pair with more thread on the front?

Re: Tyre question
It depends if it's likely to be wet, it which case probably yes.
However, the more worn pair will have a smaller rolling diameter and will therefore rotate faster for the same road speed, which the traction control will detect as wheelspin...

Re: Tyre question
In that case I'd put the less worn pair on the rear, as this will not only prevent the TC triggering prematurely but also stop the ABS thinking that the fronts are starting to lock.
Given enough hot laps, the wear might even out, unless you're really hard on the brakes.
Note that you always put the best tyres on the front, for road use, regardless of FWD/RWD, but that's much more about wet grip.

I'm a tad confused now as I always thought you put your best tyres (the ones with most tread) on the rear in a RWD car?warpc0il wrote:In that case I'd put the less worn pair on the rear, as this will not only prevent the TC triggering prematurely but also stop the ABS thinking that the fronts are starting to lock.

Re: Tyre question
I would prefer oversteer to understeer? Which is what could happen if the front has less thread?

Re: Tyre question
Oversteer will put you in the barrier backwards at 100mph plus before you even realise what is happening
The 5g sideways on your brain moving inside your skull will make sure you never realise what had really happened.
The reason I know this is the amount of times I have had cars snap round during racing and testing whilst pushing the boundaries
Eventually I got used to it as does a boxer so my brain would continue to work through the situation.
The classic example was at the clubs track day at Spa when the TVR Tuscan on loan from Ranjan boiled the brake fluid snatching a brake and sending us backwards at 140mph in a blink, I remember thinking no one will believe this and then smiling as Paula grabbed my arm before retrieving the situation through sheer luck and lots of practice at crashing
I would always put the best tyres on the back regardless of front or rear wheel drive myself, understeer can be controlled quite often where oversteer is in the hands of the Gods ( and we’re not Gods )
If it’s dry use the rsr,s and wet use the road tyres

Pete

Tyre question
I was always taught to put the better tyres on the back regardless if it was FWD or RWD

Re: Tyre question
The general rule/advice “used” to be always put the new on the front. Some years ago now that all changed and hand books etc all state the rear.
This is all pretty much down to two factors, rain and most of all sitting water on the roads!
Worn tyres offer little to no water channeling, after lots of crash data was looked at and so on showed that having better grip on the front compared to rear regardless of how much tread showed driving though large puddles that cause aquaplaning would cause the rear to spin out.

Re: Tyre question
Am guessing in the dry, I would want better stopping so I figured putting the tires with more thread on the front.
I leave TC on so can see what the car feels like and swap them. But with a small window on track just wanted to get some advice.
Honestly thought this would have been a quick answer lol

Re: Tyre question
In the dry, the amount of tread has little effect on grip.
