KitFoxers,



I recently purchased a Model IV Speedster.  The  kit came with wheel 

pants, but the builder never installed them, opting for  large tundra 

tires instead.



I would like to install the wheel  pants.  I've read somewhere that the 

tires that go under the pants are  a different size than the stock 

tires.  But I've never seen it written  anywhere as to what that size 

is.  So, some questions:



-- What  is the "standard" Kitfox tire size?



--What size tire goes under the wheel  pants?



-- What pressures does everybody typically run in their  tires?



The builder included  the wheel pants.  In reading the  installation 

instructions, there is a spindle that is used to support the  outboard 

end of the pants.



 Hi ! Nick,

                   Rex here from Australia.  I have a MKIV with Grove gear. I have Douglas 8"  steel rims. I think some have Aluminium.  The tyres originally on mine were  buffed down 2 ply ATV tyres.  In my opinion these are a total disaster.  They get prickle punctures if you go within a mile of the grass and they do  slightly touch inside the wheel pants. I think they were something like 22 x 7 x  8. I'm not real sure now.

   Anyway I've now had Lawn Mower / Golf Cart  tyres fitted for a couple of years. I really love them. So much so I have bought  new spares for when I wear them out in case I can't find them anymore.  However they hardly show any wear at all in the 2 years I've been running them..  

   Well they are Goodyear Made in USA Softrac  RS 4 Ply  18 x 6.50 x 8. They don't touch inside the pants and don't get  punctures. The one problem I did have was a valve getting bent over and  just starting to tear enough to leak.  I was running the original ATV tyres  at 9 PSI. When I first put on these new tyres I was running 14 PSI because my  friend talked me into the low pressure to reduce bouncing but as we all know  it's not bouncing anyway. This is when the tyres turned a little and I got the  valve trouble. Since then I have run 18 PSI with no sign of trouble.  

   Originally I set them up without tubes but  was getting slow leakage where the rims had some slight distortion on the inside  from the disc brake mounting lugs being welded on. So I put in the  tubes.  The other point here is that some brainless person at Douglas had  drilled the valve holes in the rims dead oppossite a wheel stud. This makes it  very arkward indeed to get to the valve to either adjust or check pressures  especially with the wheel pants on, so I have now got new tubes ready for next  fitting that have short bent valve stems. I think these will work  fine.

   I see you've got feedback re the mounting  spindles so I won't answer that as I can't tell you any  better.

   Yes these tyres are treaded and the  originals were smooth but I notice no difference and as I said I absolutely love  them . Other than the leaks as tubeless and the bent valve I never have to touch  them and the troubles are now behind me with running tubes and 18PSI. With the  original tyres we were always fiddling with them adjusting pressure, repairing  prickle punctures etc. The last problem is getting to the valve and my bent  valve stems should fix that. Hope this info helps.

I have a series IV and while I WAY behind schedule getting it

		   airworthy again I am curious about tires. I currently have some ATV

 tire on there and I'm not fond of them. I have looked at a cheap

 Carlyle tire of 16.5X6.5x8 and they might be a little heavy. What

 is normal??


	


Dave,

          Well I whole heartedly agree about those ATV tyres. Mine went in

the rubbish tin. I think your Carlyle 16.5 x 6.5 x 8 are about right.

Actually I have Goodyear lawn mower or golf cart tyres and they are 18

rather than 16.5 and if you had the choice I'd go for 18.  Mine have light

fine tread but that causes no propblem. In fact  I love them.



Rex.
