tbird Posted August 25, 2019 Share Posted August 25, 2019 I used to run 18 Fin, 20 on Skye to give me an extra couple of mm clearance Link to comment Share on other sites More sharing options...

David Brown Posted August 26, 2019 Share Posted August 26, 2019 Ran my ZZS with 24 front 23 Rear as recommended. Just had to replace my rears as centre was worn. Will try my new set with 20 rears I think. Link to comment Share on other sites More sharing options...
SM25T Posted August 26, 2019 Share Posted August 26, 2019 24/23 ... was that a hot temperature ? If cold, it might explain why middle of tread wore out first Link to comment Share on other sites More sharing options...
David aka Blue7 Posted August 26, 2019 Share Posted August 26, 2019 Finlay ... lots of discussion here:https://www.lotus7.club/forum/techtalk/tyre-pressure-touringAfter 11 years with 3 CSR's the ideal pressure is 18 psi COLD, bear in mind that once warmed up the psi will increase by 4-5 psi.BTW I am amazed you still have your wheels after a year in Glasgee ... you must have superglued them on Link to comment Share on other sites More sharing options...
Rogercsr7 Posted August 26, 2019 Share Posted August 26, 2019 I've had nearly 10 years of running with the standard 24/23 set up on CR500s, mostly touring 2 up with reasonable luggage, so not lightweight. Those pressures set cold. Dropped down to 18 all round for trackdays and occasional solo lightweight runs. Tyres have always worn quite evenly in my case. Need to switch to the ZZS set up during the winter, interested to see how they feel. Link to comment Share on other sites More sharing options...
finmac Posted August 27, 2019 Author Share Posted August 27, 2019 David - haha. Yes I did wonder but tbh the cars never been touched at all and just generates good comments. It was living inside my locked trailer in a locked palisade fence/24/7 security camera compound with a full time security guard a lot of the time though!Now moved out of the city to Kilmacolm and there’s plenty flash motors (your Aston would fit in well!) here so the CSR will be well down the pecking order!

David aka Blue7 Posted August 28, 2019 Share Posted August 28, 2019 Now that's what I call security Apologies for hijacking the thread but on the subject of CSR tyres I have a pal traveling to Stornoway in his CSR but is presently stuck at Lochboisdale, South Uist due to remarkable rear tyre damage. I have boxed up my spare rear CR500 and waiting for Parcelforce 24 to collect and deliver to him by tomorrow. The damage is quite remarkable, it looks like something has scraped and damaged the outer wall but left some intermittent ridges and all the holes seem to go inwards. The wheel rim seems undamaged. I just can't begin to guess at what has caused such damage. I wonder if there is a Q spec'd DB5 on the island licensed to shred David Link to comment Share on other sites More sharing options...

Member Jonathan Kay Posted August 28, 2019 Member Share Posted August 28, 2019 What type of tyre is that, David?ThanksJonathan Link to comment Share on other sites More sharing options...
David aka Blue7 Posted August 28, 2019 Share Posted August 28, 2019 I assume it to be a CR500 245/40 R15, which is what I have just sent him as a replacement, I don't think he ever fitted the replacement ZZS 245/40. It should look like this Link to comment Share on other sites More sharing options...

SM25T Posted August 28, 2019 Share Posted August 28, 2019 Is this what happens when the infamous Avon sidewall cracking ... that Avon says is 'purely cosmetic' ... takes a proper hold ? When I discovered this was common, I gave up on CR500 tyres Link to comment Share on other sites More sharing options...
David Brown Posted August 28, 2019 Share Posted August 28, 2019 Wonder how old Chris's tyres are. Link to comment Share on other sites More sharing options...
Area Representative Kingsley Young Posted August 28, 2019 Area Representative Share Posted August 28, 2019 My CR500’s cracked badly on the inner walls, they were older tyre’s , but not been used. Link to comment Share on other sites More sharing options...
Ian B Posted August 28, 2019 Share Posted August 28, 2019 Doesn't look anything like related to the cosmetic inner sidewall cracking.For a start it's on the outside.Could it have been driven on almost flat for some distance? Link to comment Share on other sites More sharing options...
John Vine Posted August 29, 2019 Share Posted August 29, 2019 I just can't begin to guess at what has caused such damage.Extraordinary damage. It almost looks as though the tyre has run against something with regular sharp edges, and for at least a full circumference of the wheel. It would need to have been a minimum of about six feet long, with "edges" about 2-3 inches apart. Something like a damaged cattle grid, perhaps?

tbird Posted August 29, 2019 Share Posted August 29, 2019 it's amazingly regular, even with 0 pressure in i have not seen a CR500 on the back of a CSR collapse like that Link to comment Share on other sites More sharing options...
David aka Blue7 Posted August 30, 2019 Share Posted August 30, 2019 Yes it is puzzling as to what caused the damage, when he phoned me at lunchtime on Tuesday he had just driven off the ferry at Lochboisdale but said he first noticed the problem when reversing up in a car park. The replacement tyre should be with him today and hopefully he can get the ferry to Mallaig tomorrow and meet up with us at No. 7 Bistro, Grantown as arranged. I can then get more information from him.I have to agree with the two comments above, it must have been something no higher than 3-4" from the ground because there is no damage to the rim or wing but it is still puzzling as to why it didn't damage the front tyre also? He couldn't have driven far from ferry to car park so it is surprising that he didn't hear or feel the impact? Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted August 30, 2019 Member Share Posted August 30, 2019 it's amazingly regular...Yes. Is there any structure in the tyre that matches that?Jonathan Link to comment Share on other sites More sharing options...
SM25T Posted August 30, 2019 Share Posted August 30, 2019 The phantom tyre slasher strikes again ? Maybe the tyre fitter can venture an opinion when he removes it. Link to comment Share on other sites More sharing options...
