What tyres are available for our 1974 Shadow? We have been told the V rating is not available- we currently have 4 Avon Turbosteels 235 70/R15 101V.
Where can we buy alternative ones from- we're in Ballina but frequent Sydney & Brisbane.

Peter, a lot of late Shadows are using Bridgestone SF375 235 75/R15 105S White walls which are slightly bigger in diameter. As an AIS inspector, I understand that there are no speed rating requirements on NSW registered vehicles. S rated tyres are good for 112MPH cruising. Load rating for insurance puposes is important and cannot be below factory recommendations. Points to look for: Undo wheel nuts by hand. P/S has left hand threads.These tyres have a yellow dot which lines up with the H on the rim (It is there!) Clean the rim under the hub cap. Tighten nuts with torque wrench to 50 ft lbs. Don't overinflate the tyres. I like 28psi front and 30 psi rear. Do not use an air gun. It will wreck the rims at the taper of the wheel nuts.

Peter,

I have fitted Bridgestone SF375 235 75/R15 105S to my Shadow, and am more than happy with them.

I had them fitted by Leo Geoghegan (?)in Sydney, prior to my moving north to Brisbane. The White walls are not overly noticeable, and fit in with the rest of the car.

As I recall, they were $130.00 each, fitted. I use the car most days and in 18 months have had no problems with the tyres.

To add to Graeme's advice we have about 8 cars up in Canberra with SF375's. They have been emminently successful.

Bill,

Add our two cars in Canberra to your tally. I first fitted SF375s in 1984 when they were first released, and ran their predecessors before then. You have driven both those cars yourself of course. I have run Avons, Michelins and Pirellis, but the Bridgestones are superior.

To clean the white bands (they are 3/4", so not exactly whitewalls), use 600 grade wet and dry paper with water. Done in a jiffy. Don't waste time and money using any other cleaners.

Richard;

Another why to clean whitewalls is to steal the wife's Kitchen Cleanser better if it is a brand with beach/whiteners in it. Of course this assuming your wife still uses the power instead of the newer liquid ones.

Regards,
Bill

Something that has amazed me has been the performance of Avons on the Spirits. I pounded a 1985 one up from the Coast to Canberra largely to clear its brochials and took it to my wheel aligner the next day. I was horrofied to find the steel belt hanging out of the right front tyre for 65% of its circumference. Another car low mileage could not balance them then discovered they were covered in flat spots. Yet another in fact several the shoulders just wear off in no time. These tyres are so expensive, I just wonder whether I am missing something!!!

Hi Peter,
You may like to read some of the comments at:
RROC(A) Web Forum » Technical Forum » Silver Shadow, Silver Shadow II, Bentley T-Series and T2 » Wheel rims and tyres.
I recently fitted 4 x 235 70R15 WSW Mastercraft Sensys 01 tyres to my SSII.
I live near Murwillumbah (quite close to you) and purchased them from Tweed Rubber in Tweed Heads for $660 ($165 ea) fitted and balanced incl GST.
The previous set of tyres I purchased were Toyo 800 Plus in 225 75R15 WSW, but was not happy with them - they slightly exceeded the required load index rating of 101 (@ 102) but looked much narrower, handled poorly (in my opinion) and wore excessively on the edges despite running high pressures.
Anyhow, the Mastercraft have the same wider appearance as the Avon Turbosteels 235 70/R15 which I had initially replaced by the Toyos. They are the same overall diameter saving speedo inaccuracies and feel better on the road.
I have since had them balanced on the car by Ray Hall Tyres in Murwillumbah.
And I've found a scoop or two of laundry detergent with a little water in a bucket and a cheap scrubbing brush does a great quick job for cleaning the white walls / bands.
I first wet all 4 tyres with the solution to let the detergent commence acting, then briefly scrub one at a time rinsing each as I go. Five mins they look great.
Regards,
Brad

On cleaning the white bands, I have always found that the quickest and best method is using 800 grit wet and dry sandpaper and a bucket of water. They come up sparkly white in seconds, and you can do it as often as you wish as the bands are quite thick.

Scrubbing and soap are much harder work, and the band always ends up with a slightly yellowish tinge at best.

My two bob's worth.

Well, Bill,

Although the Turbo have a larger tyre, they're still Avons.

I don't want to denigrade them, but I had a new set and they were OK, but balancing them was very tricky. When they were around 1/3 worn, I virtually gave those ugly rims and very expensive Avons away, and spent a small fortune on 17" rims mainly so I could buy Michelins. Never a wobble since, and they seem to be lasting very well.

At least Avon will sell a tyre to fit these cars. What's key is that, unless you buy 17" rims or larger, Avons are the only legal tyres for the Turbo cars. The tyre design is 25 years old and the volumes produced are miniscule, so they don't really stand a chance against a newly designed competitor.
