Continental Over-size Tyres. We have two sets of these fitted to cars and in use. One set is 895 X 150 and fitted on 895 X 135 rims. The other set is 935 X 150 and are fitted on 935 X 135 rims. The first-size seem reasonable tyres to use and should give more comfortable riding than the usual 135 m/m size. The 935 X 150 size are fitted to 2300 car and as regards wear and comfort they appear to be satisfactory so far as we have tried them. I do not recommend this large size however, as the use of them reduces the steering lock considerably. Hy.{Tom Haldenby - Plant Engineer} x917 MADE AT CROXLEY | ||
