A7 OOH Posted November 19, 2018 Share Posted November 19, 2018 Currently running my 2005 K series on 15 Wheels and considering moving to 13".Are my current hubs a Ford? and what size wheel fixings and PCD should I be looking for.Cheers Link to comment Share on other sites More sharing options...
Paul Mason Posted November 19, 2018 Share Posted November 19, 2018 Would suggest yes, ford fitting which I believe is 108pcd. Think, though please allow someone clever to confirm, correct offset is 24 (can't remember the terminology, but basically meaning the wheel is offser outward my 24mm from centre) Link to comment Share on other sites More sharing options...
Paul Mason Posted November 19, 2018 Share Posted November 19, 2018 Do consider tyre profile on 13's. I am 13's with 45 profile rear and do have some clearance issues. Not insurmountable, but one to hear in mind Link to comment Share on other sites More sharing options...
Leadership Team SLR No.77 Posted November 19, 2018 Leadership Team Share Posted November 19, 2018 Erngor, assuming you're intending to fit Caterham issued wheels, any Caterham wheels intended for use with a dedion car (both metric and imperial chassis) will fit, other than CSR wheels.Stu.

rj Posted November 19, 2018 Share Posted November 19, 2018 ET - from German "einpresstiefe" and can be translated ot inwards offset-ish.It is how much the center of the rim is offset inward relative to the flange that meets the hub. Link to comment Share on other sites More sharing options...
SM25T Posted November 19, 2018 Share Posted November 19, 2018 13" and 45 profile .... wow that sounds sump-scrapingly close to the ground !! Link to comment Share on other sites More sharing options...
Paul Mason Posted November 19, 2018 Share Posted November 19, 2018 It's actually the seat bolts that get the worst of it. If I'm on a yumpy road and hit a compression at any speed the shock through the seatbolt is transferred straight through the tillet into my spine. But, damn, she looks good and mean and purposeful. I'm all about form over function! Link to comment Share on other sites More sharing options...
K7 VCT Posted November 19, 2018 Share Posted November 19, 2018 Seat bolts here too, lowered floors and 185.60.13 tyres. Speed humps are ######## Link to comment Share on other sites More sharing options...
A7 OOH Posted November 19, 2018 Author Share Posted November 19, 2018 Thanks, so what is the ideal profile when running 13" Link to comment Share on other sites More sharing options...
Leadership Team SLR No.77 Posted November 19, 2018 Leadership Team Share Posted November 19, 2018 Erngor, profile is not a determined height but a percentage of the width, so a 205/60 tyre will have a taller sidewall than a 185/60 tyre.For the Caterham the generally considered "lowest profile" for 13" wheels would be the 175/55-13 (CR500) although availability I understand is getting more scarse, therefore Avon's ZZS in 185/55-13 would be the next lowest. Anything in the 175/55 to 185/60 profile range is fine though, front and rear. If you have wider tyres on the rear they'll most likely have a taller sidewall.They're expensive but I've found the Avon ZZS to be one of the best all round tyres I've had on the Caterham.Stu.

7 wonders of the world Posted November 19, 2018 Share Posted November 19, 2018 Take a look at Toyo R888R too available in 185/60 and 205/60 - 13 Link to comment Share on other sites More sharing options...
Toby S Posted November 19, 2018 Share Posted November 19, 2018 I run Toyo R888R's 185 60 on the front and 205 60 on the rears on 13" minilites during spring, summer and autumn (need to be a bit careful in a downpour, though) and then Yoko A539 185 60 all round during winter. I prefer the flex of taller sidewalls both from a comfort perspective plus also the warning you get before rear end break away when being a bit over spirited Link to comment Share on other sites More sharing options...
