I do like it when you get confirmation when something is shipped. I just ordered some Kumho tires and within a couple of hours TireRack sends the shipping confirmation.

I'm really excited because I've been putting off replacing the tires on the TR3. They have held up well and look in great shape. However, I bought the car over 10 years ago so they are getting a bit ancient.

What is the best tire pressure? I've been told I am a "conservative" driver. Rarely go over 70 and don't do the jack rabbit starts. I did squeal the tires once taking off from the traffic light though. Ha!

Thinking of jacking the front of the car up and putting jack stands under the cross member then jacking up the pumpkin and putting stands under the chassis near the rear spring plate. Is that a good place?

That way I can take all 4 wheels off and take them down to the tire place.

I'm planning on at least looking at the drum brakes and also replacing the LMA brake fluid while I'm waiting on the tires. Anything else to look at while the 4 wheels are off?
 
According to Triumph Service Instruction Manual, 5.50 - 15 tires, front 22, rear 24.
High speed touring in excess of 85-90 mph, increase pressure by 6 lbs.
For todays commonly used 165-15, ?
 
I recently ordered wheels and tires from a place in Miami. They were sent thru UPS as four different packages with four different tracking numbers. It was fun watching how all four took completely different paths to get here. It was as if they just went on the next truck heading North. They each had between four and seven stops before arriving here. Surprisingly, they all got here at the same time. I once made the mistake of shipping two wheels to California using the USPS. One went all the way to Cali without being delivered and then came all the way back to my house three weeks later. The box was destroyed and they could only read my address.

Should work fine. But FWIW, I normally jack under the large rear crossbrace rather than the pumpkin, so no chance of damaging the drain plug or cover. I put the front jackstands under the fore-aft legs of the frame, forward of the front crossmember, both because it's easier to get to, and because that positions the jackstands farther out. My stands won't easily fit next to the rear tires, so I also put the rear ones near either the front or rear spring attachment points.

If you have steel wheels, don't forget to loosen the lug nuts before jacking it up.

According to the owner's manual, those numbers are for bias ply Dunlop tyres. Michelin X radials take 2 psi more.

There is also a note in the workshop manual that that says "For predominantly and regularly high speed touring of continental type ... increase by 8 psi", which I think would apply to modern freeway driving.
 
Wow,
They are pretty low tire pressures.
I think I'll go with 30 front and 32 rear.
Thanks for the notes on the jacking points, etc, Randall. Makes sense - I'll do the same.
Cheers!
 
Uh, what size tires are you running?

I am concerned that you may be running way too much tire pressure. Don't forget your car weighs a lot less than most modern cars...

If all else fails drive, check tread temp, inner, middle and outer, readjust pressure to equalize temp....
 
I followed the advice here and settled on 32 psi front and back when I got new 165 R 15 tires recently. I had been a faithful 24/28 psi Michelin believer for decades and I was astonished at how lovely the newer breed of radials enhanced the TR's handling.
