Tyres for p6 rostyles - Which size
- Thread starter BBLongman
- Start date
Cheers Ali thats the one I was thinking of.
My wheel are 5" between the rims as well and are definately P5 so I'll go for the 195/50 although it's a very low profile.
Did you fit these tyres to yours Johnny, do you think there is room for a little more profile?
I've just reconditioned my wheels http://www.geocities.com/bblongman/Wheels.htm
I don't think I'll be competing with Richard Spratley's wheel recon service but it only cost me about 50p a wheel instead of £130!

Hi BB,
Just a quickie, on your web page when you say boiling in caustic what exactly does this entail, from what I understand caustic is not the sort of stuff you really want to boil, also I know you have mentioned it before on here but which acid do you use? I have an old plastic central heating header tank which looks like it will accommodate my rostyles which are in a bad way as well, thought I might give it a go.
Cheers

The caustic soda (sodium hydroxide) you can buy as a powder from hardware stores and the local one I use gives me a discount on bulk. You'll need about a kilo to every 2 gallons.
Watch out though as it'll attack aluminuim very vigourously.
Phosphoric acid is a bit of a problem as most companies won't sell to private induviduals. Ask around though as it's used in lots of cleaning products, school labs etc so you should be able to find a contact sooner or later. Phosphoric is also brilliant at cleaning aluminuim castings without the inherent problems of bead blasting.
None of it's paticularly dangerous but remember to always add acids or alkalis to water and not the other way round. Goggles are advisable small caustic burns on the arms heal but eyeballs are a bit more delicate!
Well worth getting yourself set up as it makes restoration of rusty bits of car a pleasure rather than a chore.

Hello BB, I found that the closest circumference to the 185/80 - 14 profile is 195/70-15 in the wheel and tyre bible :

Hi Bennett,
A tyre width up to 205 will fit --- the Denovo tyre was 205 section, 65% profile on a metric wheel of 375mm diameter. However, if the P5 wheel offset is different from the Denovo then a 205 tyre on a P5 Rostyle could scrub the wheelarch when cornering. Try a used 205 tyre on a Rostyle at each corner and see what clearance you have; then you know that a 195 will also fit. Check the rear in particular --- compress the suspension by jacking the car up.
A 205/15/65 tyre has a rolling radius of 99.4% of the original 185/14/80. A 195/15/70 is fractionally nearer to the original at 100.4%. These differences are academic, and are of no practical significance.

Cheers John, I'll definately experiment first. Your right about the rear; I was very suprised to see how close the back of the tyre runs to the rear chassis leg although I think it must move out as the suspension is compressed and the driveshaft becomes more vertical.
Not to worried about rolling radius as the the speedo will need recalibrating anyway.
