Tire Pressure

[LuckyFloridaLin@aol.com]

Dear Lads and Lassies; This is a some what innane question. What pressure does one use on 19" Garfield Tyres? Currently using 28 poundsand it doesn't feel correct. Should I increase the tyre pressure for better control and handling. Perhaps I am at the mercy of the Bishops Cam. Tally Ho! Thom Collins

I used to run my TA on higher pressures but felt that this just increased the vagueness. Reduced to recommended 24psi front and 26psi rear for the Tulip Rally the other week and found the handling (and comfort) much better. I run the Bishops Cam too. For twisty mountainous roads I use 16" rear wheels with 5.50 tyres. Not only does this reduce the axle ratio somewhat (about 16%), roadholding is much improved and we don't throw tyres or break spokes on bumpy twisty stages. Brian

I have now checked my figures (and my tyres!). Using a Halda tripmeter set up for 4,50x19 Dunlops I get a reading of 8.64 km instead of actual 10 km (measured against Motorway distance posts) when using Dunlop SP TA(XI) 175x16. Forgot that I changed from the 5,50x16 to get a better tread. the actual difference is then 13.4%.

I can't explain it either, but acceleration is so much better, as the hillclimbing ability. Brian

Brian, How do you arrive at your 16% figure? I have been under the impression that the effective change in rear end ratio was around 4% when going from 4.50x19 to 5.50x16. Where have I gone wrong? Thanks for your input. Cheers, Old Arch (Jack Archibald TC5050)

Dear Arch You managed to get the old grey matter working (no mean feat on a Sunday!) and I have just measured the diameter of the tyres concerned. Both the 175 x 16 and the 5.50 x 16 measure 69cm, the 4.50 x 19 (now somewhat worn) 73.4cm. Mathematically 6% less for the 16". Still don't understand the Halda readings though. Or just a thought. Since zeroing the Halda in to the 19 tyres I've replaced the diff. Both were supposed to be the same ratio, ie standard TA? Back to the measuring board! Can someone remind me again how to check the diff ratio, ie how many times should the propshaft turn in relation to the wheels.

I said that the old grey matter doesn't usually work on a Sunday! the Halda readings should be the other way round, ie. 10 km on 16" rims read 8.64 km on 19". Hope you're all now totally confused!

I know this is like asking what wine is the best, but what do you all recommend for tire pressure? I seem to recall there was a thread on this not too long ago, and I thought the recommended pressure was 30 psi. In driving last weekend that seemed a bit harsh. The Brown book says 24 psi front and 26 psi rear. Blower says 24 psi for both. Is this all up to personal preference? I'm having the front end aligned tomorrow and would like to go in with the tires at the pressure I expect to use. Thanks Doug Pulver TC 5850 San Diego, CA

Hi Doug Pulver, There were different recommendations for tyre pressure from the members. This is mainly because of different tyres manufactures. On most of the new tyres you can see pressure recommendation for normal road conditions. Check the pressure on a cold tyre only. The tyre with low pressure you will have extensive wear out on the edges. If the pressure is too high you will have too much of wear in the centre of the tyre profile and gives a rough ride with better rolling resistance in dry weather. Do not forget the bonus for your body weight. Start with bit higher pressure. if it is too rough you can always release the pressure. Please go the Tyre manufacture's web site and read the new information they have. http://www.dunloptire.com/care/sidewall.html Madhu -----Urspr ngliche Nachricht----- Von: DougPulver@aol.com [mailto:DougPulver@aol.com] I know this is like asking what wine is the best, but what do you all recommend for tire pressure?

In my experience you're better going a couple of psi higher all round - certainly gives significantly better roadholding, particularly with Waymasters.

I have worn out a set of tyres in the center by running at 24psi, the edges still had plenty of life. I am now trying my new Dunlops at 20psi. The roadholding is still OK, but I am aware that low pressure at the back gives oversteer, and is a sure sign of a puncture. Neil Sharpe TA 0319 Worcester UK

since the TC tends to oversteer I run 32psi in the back and 30psi in the front on Firestone tires. Ron Simon --- neil sharpe sharpe270@btopenworld.com> wrote:
