| √20 X. 1299 Extract from Mr. Platford's report re Cars in Spanish Grand Prix. - in X. 387. Prowodnik Tyres were very satisfactory, rubber treads only and gave no trouble, but were certainly badly worn after the race. Mr Salamanca's car would not have done another lap. For heavy touring purposes they were also very good 2500 to 3000 miles. Continental tyres also seemed to run very well. I noticed on competitors cars after the race that they were in very good condition.
