Need help deciding wheel and tyre size.
Hi Guys
I need to buy some wheels and tyres and I don't really know what size I need. I have a Hayabusa ( 1.043 6th) and a 3.14:1 diff. I will use
mainly on the road with the occasional track day.
any suggestions?
Cheers
Jason

Other than deciding on gearing - if you do a search on this site there's a good calculator about - it's really down to identifying your
priorities.
13" rims will give you the least unsprung weight, a good selection of (cheaper) trackday type tyres and possibly the most forgiving drive due to
having a little more compliance in the tyre sidewall.
But.... 15" look better I wouldn't bother with 14" or 16" due to the limited tyres choices out there. IMHO 17" is
too big for a locost type car.

I have the PPC gear calculator with the 'Busa ratios plugged in and a tyre size calculator. All you'll need to do is type in your diff
ratio and start inputting different tyre sizes to get the in gear speeds you want. Send me your email address by U2U and I'll send you a copy.

13" - Westfield MegaBusa factory fitment.
Split rims (e.g. Image BRM) will allow you to easily change the width as you change your mind from road use (185-295/60/13) to wider slicks and the
track.
Plethora of tuning folk will then get that engine out to 1400-1600cc...

I went for 16" but had a hell of a time finding matching 7" wide and 8" wide wheels... was also very limited on tyre choice for
that size.... Basically if Toyo stop making them i'm screwed!
I do think the 245/35/16s look nice on the back though

Neither 12 nor 14 shall the wheel be, for the wheel shall be 13.
Yes, 13" is the Holy Grail of wheel sizes.
