tire skinny as I see it..
Gooney,

The Tire Rack
sold me
BF goodrich 255/60/15's for around $70 , a rep called me personally to talk C3's and mods. I think they might be legally obligated to call, but they were also very curious as to what I was doing. I think they are selling lots of 255's to C3 owners these days and want to know what were running into during the installation. Thats the impression I got anyway.
They were on my doorstep in 3 days UPS.
Tire pressure changes drastically with the seasons ambient temp and road surface temp, and driving conditions, I may be a bit anal here, but I deal with it like this..
I always have a good pressure guage in the car, and air the tires up to 34psi cold if going driving long distance straight down the hiway, and keep the pressure at 38-40 for the long haul(good mileage).
34psi constant around town.
I spend lots of miles on winding roads and high speed cornering, , so I drop the pressure in all the tires to 30-32 when out exclusivly on the twisties, the tires stick a bit better, at the cost of gas mileage.
This kind of formula seems to work well for me, I havent noticed any abnormal tire wear.
...The dreaded C3 park brake mount bracket issue....
Ive never heard of 245's having the brake mount bracket issue. 255's on up "can" have the bracket clearance problem. If you got a little space there after mounting them, Drive it and check the sidewalls closely for awhile. check them again if you do any suspension work , alignment, struts, sway bar. This is where I got into trouble. I didnt have any clearance problem until I installed a rear sway bar. Then I quickly ruined the passenger side rear tire? Why the clearance changed, I dont know?? But I relocated the brackets and replaced the tire pronto, now everythings just fine back there, My suspension upgrades are all working like they are supposed to.
Good luck..
