i believe the revo original tire is only 4ply. for the weight capacity of revo, 4ply is insufficient, that's why nagbukol yan. Go for 6 or 8 ply, even with the same specs.
highly recommended 8 ply sa auv pero 6 ply is safe na. major brands like bridgestone, dunlop, pirelli, GTradial and michelin all have very good performance. wag goodyear, lagi bukol yan. take it from me, been in the tire business for 18 years.
mga bossing, pasingit lang po regarding tire sizing, is 235/75 the same as 30x9.5 size tires? the former is in metric/aspect ratio but how do you read 30x9.5? Is it a direct measurement of overall diameter and tire width like 30x9.5 = 30" diameter and 9.5" tire width? which one would yield a wider footprint and taller diameter in a 15" rim? TIA!
