I think we have some good news at Longstone tyres
 
 

 
Good topic!
 
I am for ever scouring wrecking yards looking for Goodyear Grand Rally S 175 13 tyres in good condition for my daily drive "BabyBlue" (piccie below) . Also Goodyear Super Steels 175 13 for the RS2000.
 
I choose these tyres because they are period correct and manufactured in Australia.
Part of my projects is to exclude anything manufactured in china.
 
 
 
 
 
 
 
 
 

I have 12" wheels on my Escort and want 155r12 tires. Not a lot of choice out there. Would love to get something period correct and manufactured in Australia. 

Well there are 2 bits of good news:
1/ we already have 185/70VR13 Pirelli Cinturato CN36 https://www.borrani.com/pirelli-tyres/cinturato-cn36/185-70vr13-pirelli-cinturato.html which i beleive was an option on a MK1 RS1600 and twin cam Mexico
2/ hopefully in the near future we will have a 175/70R13 Cinturato CN36!
 
I will let you know when i know more.
