Couple of interesting things to read:

1st testing 3 DOT R-compound tires, "Barely Legal"

http://www.musclemustangfastfords.co...gal_tire_tests

2nd Tyres, Grip and All That...Sorting fact from fiction in tyre physics

http://autospeed.drive.com.au/cms/A_108915/article.html

I liked the 1st one 'cause I need affordable track performance tires, and the 2nd one because...well read it and you may be surprised what you learn about w-i-d-e tire performance.

Enjoy

 

very interesting.......had to read the autospeed article a couple times to wrap my head around it.

 

Good find, thanks.
