TR2/3/3A Randall...Re: tire pressures

In one of your posts you mentioned that the tire pressure in your rear tires is 34psi. I am running 195/65 tires and have always run 30 front and 30 rear. In terms of weight distribution and the particular handling of the TR3 would it be advantageous to increase the pressure in my rear tires? I
 
Too many complicating factors for me to say, Karl. My suggestion is to try it (carefully) and see how it works for you.

That's how I got to what I like. The 'carefully' part (for me anyway) was that I had to throw the car into some tight corners to see what happened. You're starting with oversteer so the front to back pressures are a matter or whether you want more or less of that. Overall the pressures will affect the ride.
 
Funny, there's nothing in my manual about what pressure works best with modern tires. Not even a good definition of "best" :smile:
 
Another factor to consider for front tire pressure is how it effects worm & peg steering.
I took Forum advice a year or two ago and started running my front tires at 33 psi.
to make steering easier at parking & slow speed.
FWIW: Allen Hendrix of Hendrix wire wheels, recommended 30 psi rear (I presume for better traction / bigger footprint) & 32-35 psi front on new
Vredstein Sport Classic 185x15 on TR3 with standard steering.
I have no complaints on how they handle.

Mine has an entire page of pressures, but I'll bite...how do modern tires affect the recommended pressures?

Sorry guys, but threads like this are both never ending and have no real answer, just a lot of opinions. Best tire, best pressure, best oil, etc. Jaguar is my favorite, as their manuals spell it out for you...if you want smooth ride and more comfort, use a lower pressure. If you want a firmer ride or plan to drive "spirited", use a higher pressure. So the best pressure would, therefore, depend on your style of driving.

As with spark plugs, learn to read wear patterns and figure out what your style requires.
