I'm new to Paul's tires, when shopping on Slot Car Corner, I can choose between a PGT part number or an XPG part number? I cannot seem to find any explanation of the difference anywhere on the internet. Please advise.

The difference is the shore rating, or softness. PG’s are 40, XPG are 20. Lower the shore number, the softer the compound.Scott.....War Eagle River......Tampa, Florida, USA

I've gotten to prefer XPG's because they go on the wheels easier. Not easy, just easier.
Just about all my cars have plastic press on wheels and not having to wrestle with the rear axle as much during tire replacement is nice. I popped a rear wheel off a Pioneer Camaro putting PG tires on it and have been more cautious since then.
I have not done track testing to see which compound works better - I just put the tires on and go racing.

I'll try that. I used to think spittle was a special medication to be reserved for skinned knees and elbows. But since I haven't skinned a knee while playing in several decades, no reason not to re-purpose it now. -
Be sure to keep your favorite beverage handy to wash out the taste of plastic or aluminum afterward. I can’t imagine slot racing not involved spittle. How else can you pick all the little spacers we use? Or clean tires in a hurry? Maybe I should start a new post on the many uses of spittle in our hobby.

If anyone wonders if putting PG (or XPG) tires on a car really makes a difference, just buy a pair and do before and after time trials. The one lap difference may not be huge but it's consistent. A tenth of a second or two of reduced lap times over a session really adds up.
