petefoster Posted March 28, 2010 Share Posted March 28, 2010 POBC I am in need of wisdom, which of the scudo's should I fit to my 15" wheels 🤔 and probably more importantly why 🤔 🤔 🤔 195/45 195/50 205/50 to be used in anger in the sprint championship *evil* I plan to live for ever...so far so good!!!

myothercarsa2cv Posted March 28, 2010 Share Posted March 28, 2010 Assuming ground clearance isn't an issue, go for low pro - the smaller the diameter, the more acceleration you have.

Area Representative Richard Price Posted March 28, 2010 Area Representative Share Posted March 28, 2010 Pete, I've been using 195/45-15 Stunner Scudo's. I chose to use 45' rather than 50's, to keep the gearing and ride height lower. Link to comment Share on other sites More sharing options...
Stationary M25 Traveller Posted March 28, 2010 Share Posted March 28, 2010 My 15" wheels are fitted with 195 x 45 (CR500). 50's wouldn't fit under the arches. Link to comment Share on other sites More sharing options...
Dave Wilson Posted March 28, 2010 Share Posted March 28, 2010 A 50 profile will give a bigger contact patch for the same tyre width. I've run both 45 and 50's and preferred the feel and grip of the taller tyre. Ken Evans used 45's to good effect on his Superlight 3 years ago, I tried them and switched back to 50's on my VX car.

7 wonders of the world Posted March 28, 2010 Share Posted March 28, 2010 Assuming your not taking camber and sidewall distortion into account the contact patch on the 195's is the same. Too young to be old ! Link to comment Share on other sites More sharing options...
Leadership Team SLR No.77 Posted March 29, 2010 Leadership Team Share Posted March 29, 2010 No, 50s will have a bigger contact patch (but not by much and whether it's noticeable is questionable). The contact patch is longer not wider. Stu. Link to comment Share on other sites More sharing options...
petefoster Posted March 29, 2010 Author Share Posted March 29, 2010 Thanks Guys, just one final question, what about 205/50's on the rear and 195/45's on the front, any ideas what that may do for handling or ride comfort? One concern is having moved from 175/55 13's I am thinking the 45's might be a tad firm and given I have tillets as well, the ride to europe in june could be a bit of a bone shaker but with the 205/50's on the rear this might improve comfort The stats below show that the 205's won't fit under the front arches as I still have the 13/14" stays and wings but the 195/45's do, but the 205's should easily fit the rear arches. I think I read somehere the slightly nose diving setup this would give may improve handling, but am not sure so would much appreciate any advice Specification Sidewall Radius Diameter Circumference Revs/km Difference 175/55-13 96mm 261mm 523mm 1642mm 609 0.0% 195/45-15 88mm 278mm 556mm 1748mm 572 6.5% 205/50-15 102mm 293mm 586mm 1841mm 543 12.1% I plan to live for ever...so far so good!!!

Stationary M25 Traveller Posted March 29, 2010 Share Posted March 29, 2010 Have you got adjustable platforms, so you can fine-tune heights ? Link to comment Share on other sites More sharing options...
petefoster Posted March 29, 2010 Author Share Posted March 29, 2010 I have, so would I need to 'level' the car up again Link to comment Share on other sites More sharing options...
Area Representative Nick Chan Posted March 29, 2010 Area Representative Share Posted March 29, 2010 Hi Pete, more upgrades for class 1 I see 😬 WRT the tyres, I would stay on the same width all round to make things easy for switching tyres round if needs be. i have travelled to Europe several times with 195/50 ad 195/45 Stunner Scudos and both are absolutely fine with the tillets. Have you found a UK distributor for Stunners? I have asked at a couple of places and both said they were now unavailable here. Cheers Nick Back in a BEC! - but done alright in Class 1...

Stationary M25 Traveller Posted March 29, 2010 Share Posted March 29, 2010 I mentioned it in response to your comment about 'nose-diving' set up. You are looking for rear to be 15mm higher that front, when car loaded with driver, or driver and passenger if that is normal loading. Plenty of recent threads about setting heights if you do a search in TT. Link to comment Share on other sites More sharing options...
Dave Wilson Posted March 29, 2010 Share Posted March 29, 2010 205's on the rear and 195/50 on the front should be a nice balance, especially if you're wishing to use the car in competition. I found a noticeable difference between 195's in 45 and 50 profiles, the 45's I felt gave up grip a little more suddenly that the 50's. Perhaps it was due to the extra weight of my car over a Superlight, but I had to change them mid season. There is a reasonable increase in contact patch between the two profiles, give Paul Smith at BMTR a ring for the full technical explanation.

Graham Howard Posted March 30, 2010 Share Posted March 30, 2010 Nick I bought some Stunners from Pneus Online last year and they still seem to be available, here: http://www.tyres-pneus-online.co.uk/car-tyres-195-45-15.html Graham Link to comment Share on other sites More sharing options...
