Tyre Sizing
Posted: February 20th, 2015, 1:17 pm
Hi Guys
I am looking to get some tyres to fit my Ford Capri where i have 15" Alloy Wheels.
The Front Rim width is 8.5" from face to face & the Rear Rim width is 9.5" from face to face(outer faces)
I do not want any stretched looking tyres, but i am also looking for something that is fairly close to the original diameter of the car, if not a bit smaller.
I am not overly concerned about speedo error as the car is being built as a Track/Race car.
So far i am looking at 215 or 225 for Front & 235 or 245 for Rear.
I have had a look online but cannot find a decent comparision calculator, does anyone know of a good online calculator that they can recommend?
Obviously once i have found a size i need to buy tyres as i am looking at refurbishing the wheels currently in order to get the car rolling on its wheels this summer. I need to do this as i need to simulate whether or not i have enough clearance in the standard arches to fit these wheels. They are alot wider than most would run but they should work well with the other modifications on the car. I have a set of cut down leaf springs to help me simulate full bump and where approx the wheel will be. This will also help me decide if i need to look into designing a Watts linkage straight away.
It may be that i have to look into either narrowing the rear axle, flaring the arches or buying new outer rims (3 piece wheels)to fit correctly.
All help much appreciated.
FYI Standard wheel size on a Capri is 165/65/13 (steels) or 185/70/13 (4spoke alloys) on 4 cylinder or 205/60/13 on 2.8 or 195/50/15 for Capri 280.
