SteveP Posted September 5, 2002 Share Posted September 5, 2002 Thought I'd share this with you all now that my new 13" rims have arrived! KN Minators 6 x 13 23mm offset, 185/60 RE720s, switching from 6.5 x 15, 13mm offset 195/50 Michelins Fronts fit a treat but look a little lost under the 15" arches! Easily fixed, CF here I come The rears do foul on the DeDion ear (ever so slightly), but enough to scrape and would knock off the balancing weights. Easily fixed by adding in a 3mm wheel spacer - no more problems Mine is a 1989 DeDion BTW, so probably has the older style Ford hubs (i.e. holes between the studs) Just adding weight to things that have been said in the past on Blatchat, spot on advice and a big thanks for everyones input. Not driven it yet, will find out what it's like tonight! And a quick plug for Raceways at Donington Park Circuit - superb service, from order to pickup in 3 days - no connection other than a very satisfied customer. A quick question - what is a good tyre pressure for this wheel tyre combo? - engine is a xflow SteveP Edited by - SteveP on 5 Sep 2002 14:28:35 Link to comment Share on other sites More sharing options...
Vanessa Morris Posted September 5, 2002 Share Posted September 5, 2002 ? KN Minitor should be 24mm off-set when used @ 13" x 6" size. Supplied 100's without fitment concern? Link to comment Share on other sites More sharing options...
TonyR Posted September 5, 2002 Share Posted September 5, 2002 Vanessa, "Supplied 100's without fitment concern" I'm looking for a new set of four 6 x 13 wheels for my Superlight. Please e-mail if you can help. TonyR Link to comment Share on other sites More sharing options...
SteveP Posted September 6, 2002 Author Share Posted September 6, 2002 Vanessa, I can only talk about my car, but 23mm offset touches the DeDion ear, any more offset and I'd be in trouble! The ideal offset for my car would be 20mm at the back (effectively what the wheel spacer gives me) The guy at the KN factory said that 23mm is the one they supply direct to Caterham, and 16mm for the 7" rim - the wheels received were certainly stamped 23. Just my experience, that's all. As for was it worth it? - only had a brief drive, but first impressions are a slightly more compliant ride, better turn in (although that could be the rubber) and slightly improved acceleration - aesthetically, I think that they look a load better than my old Prisoners, but that's just my opinion. Plus new wheels gave me a 3kg weight saving per wheel SteveP Edited by - SteveP on 6 Sep 2002 09:21:35 Link to comment Share on other sites More sharing options...
puremalt Posted September 6, 2002 Share Posted September 6, 2002 The owners book says 20psi for 13 &14 " wheels. Nearly lost it out of a roundabout yesterday, with a6"kerb on one side and a car transporter on the other! Dave Robertson Link to comment Share on other sites More sharing options...
scooby dooby doo Posted September 6, 2002 Share Posted September 6, 2002 depends on the tyres a bit. but 20 won't be too far out (although a bit high for softer tyres - A032Rs will want about 17 for example) HOOPY CYCLE WINGS CUCUMBER Link to comment Share on other sites More sharing options...
V7 SLR Posted September 6, 2002 Share Posted September 6, 2002 I can only talk about my car, but 23mm offset touches the DeDion ear, any more offset and I'd be in trouble! The ideal offset for my car would be 20mm at the back (effectively what the wheel spacer gives me) Hmm, isn't "offset" the amount of mm from the hub-face to the outer edge of the wheel (you appear to be describing "inset")? In which case what you actually need is more offset. I think Vanessa is right that you need 24mm or more.

SteveP Posted September 6, 2002 Author Share Posted September 6, 2002 V7, My understanding of wheel offset is it the distance between the centre line of the rim to the mounting face of the wheel, and can be measured in both positive and negative. So a positive offset means that the mouting face of the wheel is x mm closer to the outside of the rim of the wheel and so more of the wheel is placed "into" the car - the larger the offset, the more of the wheel is into the car. So in this example, 24mm would mean an extra 1mm of rim would be interfering with the DeDion tube. A negative offset is the reverse meaning the wheel will "stick out" more from the car - typically negative offset wheels have that "deep dished" appearance associated with very wide rims.

scooby dooby doo Posted September 6, 2002 Share Posted September 6, 2002 Steve P is right - its from the centre line to the hub face. HOOPY CYCLE WINGS CUCUMBER Link to comment Share on other sites More sharing options...
Vanessa Morris Posted September 6, 2002 Share Posted September 6, 2002 Yeap, from center line of wheel to bolting face of web. Offset can be positive and negative. The 6" wheels supplied were ET24mm The 7" wheels supplied were ET18mm These sizes are well known to KN with the 7" being developed in conjunction with KN & myself and now being offered by Caterham! The reason for the reduced amount of offset on the 7" was to ensure that when mounted with tyres they would not protrude outside the standard guards. As for the question about supply - Sorry Ca%erhamham have shut the shop on my bulk purchase efforts! However, I notice that others are trying so good luck! Hope this helps with the mystery Link to comment Share on other sites More sharing options...
V7 SLR Posted September 6, 2002 Share Posted September 6, 2002 Ahah. I see. Thanks for clarifying that. Worcs L7 club joint AO.//Membership No. 4379//Azure Blue SLR No. 0077//Se7ens List Tours Link to comment Share on other sites More sharing options...
murph7355 Posted September 6, 2002 Share Posted September 6, 2002 The best way to shut down bulk buys is to use your own purchasing power (Big Brother) and sell at a very attarctive price to make going it alone unattractive. Especially when the man helped sort the bloody offsets out! Understand also that the people buying on these bulk buys will not suddenly think "ah well, can't get them cheaper so I may as well bobby off down to Caterham for a set". They'll either try and get discount themselves direct or, more likely, will simply purchase from any number of other places. That way you lose out AND the manufacturer does. And you can't lock out all wheel manufacturers doing hubs with Ford fittings you know (you could, of course, design a completely bizarre hub if you wanted to). And if you can demonstrate absolute reasonableness with your pricing, the knock on is that us 7 mugs will end up spending even more when we do pop down for wheels, aeroscreens, carbon parts etc Because I'm a nice guy, if you're reading you can have that advice for free.

Rob Morris Posted September 6, 2002 Share Posted September 6, 2002 Oopp's! Call myself an Engineer and I can't even get the offsets' correct! 6" wheel = +23mm 7" wheel = +18mm Don't know where I got the 24mm bit in my head from 🙆🏻 Good luck to the new bulk buy & if I can help in anyway feel free to call (01952) 242786 Rob M. 40th Anniversary Vauxhall Man www.slipstream-trackdays.co.uk Link to comment Share on other sites More sharing options...
