O.K, a few phone calls & problem averted.
Sorry Mr Saddlebags, gonna stick with my 225/50/15s & 5 spoke alloys.
And won't be buying your Wolfies I'm afraid Mr Pie.
I really fancied some deep dished rims, rather than the flat fronted ones I've got, but just not worth the hassle, especially at this late stage in the build.
So. Mr Loony senior's going to buy the 295s when they arrive & fit them on his Wolfrace rims for his Camaro. That'll give me the cash to reMOT the bike & tax it in time for the toy run in 2 weeks time.
I was seduced by the thought of big fat rubber, but the trike's got to be rideable so I'll stay mildly sensible.
Of course, Flap's promised to remind me of my folly every day for the rest of my life
