johntr6 Posted July 2, 2011 Report Share Posted July 2, 2011 Hi, I am looking for new tyres for my TR6 and there doesn't seem to be a lot of choice and good prices in Radials 185-70-15.However there is a much better choice and sensible prices on 195-65-15 Radials. Would 195's be suitable for a 73TR6 Thanking you Regards John Quote Link to post Share on other sites

TRTOM2498PI Posted July 3, 2011 Report Share Posted July 3, 2011 I have 195/65/15 on standard TR6 wheels on my TR6. Tyres are Pirelli P6000 - £220 for 4, fully inclusive. Cheers Quote Link to post Share on other sites
bigfella Posted July 3, 2011 Report Share Posted July 3, 2011 I'm in the same boat, standard wheels and wondering which tyres to go for. Speaking to Longstones they recommend 165 x 15 's - which were original spec I believe - i'm on 185 x 15's at the moment. Can't help but think those 165's are awfully thin !!!

bigfella Posted July 3, 2011 Report Share Posted July 3, 2011 Would be interested to hear thoughts on the 195 x 65 x 15 on standard 5.5 wheels - if these are ok then I think i'll go for a set rather than opting for the 165's. I can get hold of them locally also rather than a special order ! Quote Link to post Share on other sites
TRTOM2498PI Posted July 3, 2011 Report Share Posted July 3, 2011 195/65/15 are the ultimate tyre size to for for on a standard 5.5" TR6 rim. This is what I use. Cheers Quote Link to post Share on other sites
67_gt6 Posted July 4, 2011 Report Share Posted July 4, 2011 (edited) If you go higher than 185/70 you will lose much of what makes the IRS cars good to drive. The car will feel "floaty" and when the rear goes it will do quickly, whereas with the thinner tyres the rear contact patch changes much more progressively.

Tom Fremont Posted July 4, 2011 Report Share Posted July 4, 2011 I've got 195/65 - 15 Michelin Pilot Exaltos on 6" Panasports and they do almost as well as the 185-15 Michelin XAS tyres on my show car ( 185s are NLA in the XAS ) Diameter of the 195/65s is ~ 0.4" smaller than the 165-15 originals, but that's very close. I have never been confident of the proper inflation pressures to use with these. 30/32 now, up from 25/27 before. Reckon the footprint is quite different from the 165s; probably short and wide vs. long and thin. Anyone know? I'm considering going to 165-15 XAS once the Pilots wear out but have concerns about the 6" wheels - anyone know better ? Splash cover is compromised with fatter tyres, inertia increases and you may never know what the optimum operating pressures are. For 5s and earlier vintage appearance is another consideration.

D1070 Posted July 4, 2011 Report Share Posted July 4, 2011 I changed from Goodyears to Pirelli a few months back. The rims are the standard minator minilites at 6''. Size 195/65-15, seems just about right to my mind, plenty of feel and grip but not soo heavy at parking speeds. The P6 cinturato has a classic tread pattern which looks right on the 5, IMO of course ,-no complaints after 3500 miles, cheers, Laurence Quote Link to post Share on other sites
Denis Posted July 4, 2011 Report Share Posted July 4, 2011 (edited) Surely wider size tyres (which make TR's look like Beach Buggies IMHO) invalidate you car insurance, as they're not the ones recommended by the manufacturer? Also, you will have a car that has far too much grip for it's chassis design? Edited July 4, 2011 by Denis Quote Link to post Share on other sites
bigfella Posted July 5, 2011 Report Share Posted July 5, 2011 Hmmmm Not sure about the insurance aspect. I do know that when I rang Longstones they were advising that 165x15's were the correct tyre. I have 185's on at the moment - difficult size to get hold of. Seems people like the 195 65 15 tyre which has better availability / price and this has got me interested in that tyre size.

tallpaul Posted July 5, 2011 Report Share Posted July 5, 2011 (edited) Hi John, I'm running on standard rims with Michelin MXT 195/70/15 fitted. No complaints on steering input or handling. Edited July 6, 2011 by tallpaul Quote Link to post Share on other sites
Denis Posted July 5, 2011 Report Share Posted July 5, 2011 Don't do it! Far too fat! it'll squige around on it's floppy side walls! Nothing wrong in the correct size tyres it's chassis and road holding were designed around! Quote Link to post Share on other sites
Quentin Posted July 5, 2011 Report Share Posted July 5, 2011 (edited) Vredestein T-Trac 165 80 x15s for me. £220 fitted (all 4). I was pursuaded that the 165s would give better handling but slightly less soft ride. You could look at this topic if you are interested. http://www.tr-register.co.uk/forums/index.php?showtopic=27820&st=0&p=203029&fromsearch=1entry203029 It also has a mixture of opinions. I went for Alec's advice in the end. Meanwhile the T-Trac is also very well reviewed on various review sites. Edited July 5, 2011 by Quentin Quote Link to post Share on other sites
johntr6 Posted July 6, 2011 Author Report Share Posted July 6, 2011 Thank you chaps, it looks the 195's are the majority. I have 185's on at the moment so 195's will give me better choice/price Regards John Quote Link to post Share on other sites

(think of elections! ) But if you do go for the non standard size make sure you tell your insurance company that you have modified your car! As they will find the slightest excuse these days to get out of paying a claim! Quote Link to post Share on other sites
Willem Posted July 6, 2011 Report Share Posted July 6, 2011 Vredestein 185 HR15 TL 91H VRED SPRINT CLASSIC Much more comfort and handling than the former 205's Quote Link to post Share on other sites

(think of elections! ) But if you do go for the non standard size make sure you tell your insurance company that you have modified your car! As they will find the slightest excuse these days to get out of paying a claim! The original size was probably an 82 or 83 profile, so fitting 80 profile is modifying the car! One of my cars came with Crossplies as standard, another came with a tyre size that is now only available as an 8-ply van tyre. Both are standard, at least 1 stands a good chance of killing me, insurance companies expect cars originally fitted with crossplies to probably have radials now fitted. Was 165-15 standard for every model TR6 in every market? I expect the Americans got bias ply tires (get the spelling correct!), did the size change if you chose steel rims or spoked wires? Unless you have a copy fo the build sheet, there is a fair chance you will not know how it left the factory. Cheers Colin Quote Link to post Share on other sites

The reason most people use 195`s is because they are cheap as virtually all run of the mill cars run that size these days. However you do need to bear in mind tyre technology has advanced huge amounts since these cars were new and so has chassis/floor pan technology as well and the amount of grip with modern tyres can put very high loads on suspension mountings/drive lines that they weren't designed to take even allowing for the certain amount of "over engineering" that was built into everything back then.

Stuart. Interesting I find that my 195/65-15 Michelin Pilots grip nearly as well as the old style 185 XAS tyres; not better. I reckoned Poly and nylon bushes would exact a higher toll on suspensions than modern tyres, though especially large/wide ones can certainly pound them into submission Quote Link to post Share on other sites

Bushing would depend on the type/quality as some of the harder type do transmit rather than insulate. Stuart. Quote Link to post Share on other sites
Tom Fremont Posted July 7, 2011 Report Share Posted July 7, 2011 Is that in the wet or dry? Dry. I wouldn't push the XAS in the wet but then they're too old ( 2001 ) to push much now anyway Quote Link to post Share on other sites

I wouldn't push the XAS in the wet but then they're too old ( 2001 ) to push much now anyway Just goes to show how good the XAS`s are then when 40 year old tyre technology beats new century type though I suspect the Pilots in a back to back all weather test with new XAS`s (If they still made 185`s) would probably outshine in the wet.
