Answer:

Pressure in the tire is 62.32psi

Explanation:

The following were obtained from the question given:

P1 = 66 psi

T1 = 50ËšC = 50 + 273 = 323K

T2 = 32ËšC = 305K

P2 =?

Using P1/T1 =P2/T2 we simply calculate the new pressure as follows:

P1/T1 =P2/T2

66/323 = P2/305

Cross multiply to express in linear form

323 x P2 = 66 x 305

Divide both side by 323

P2 = (66 x 305) /323

P2 = 62.32psi

pressure in the tire is 62.32psi
