Hi I am new here i have a 78 911 sc 60k original car which i have owned for many years.I have a question about the wheel and tires on my car it has 16inch bbs wheel and at present has 225 50 r 16 on the rear but it looks like i could put a larger tire on,is this possible?also i have lost the manual over the years and there is a red light on the dash that is flashing with the letter G in it what would this be?

Thanks for any help

Kurt

 

You could maybe squeeze a 245 x 45 x 16 on the rear.....

The red flashing is the handbrake warning light. Does it go out when you release the handbrake?

 

The light stays on when i release the brake,it is the little red light in the guage cluster with the temp guage and below the green light with the marking OEL it has a G with a circle around it and i am thinking it might be a generator?not sure

 

Yep, that light is the alternator. Mine stays on when I first start the car but goes out as soon as I rev the engine. If ours doesnt go out then it would see you have a problem with the alternator.
