Continental ContiCrossContact UHP 235/65 R17 FR 104V

For the given tyre size, the tyre pressure between 32-34 psi can be ideal.

Choosing a tyre size other than the company-fitted one leads to a drop in fuel economy and performance, hence tyre upsizing is not recommended by the bike manufacturers. Moreover, the choice of 150 widths is good for those who go for track rides more often, and 140 widths are ideal city space as it manoeuvres easily across traffic. Based on this, you can take your decision. Another thing is if you opt for 150/70 tyre size, most of the tyre brands use soft rubber compound in the making which leads to quick wearing of the tyres.

For optimum stability and control, it is always recommended to replace tyres in pairs. Moreover, as the tyres have already done 25,000 km, you can opt for two new tyres and keep the other tyre for spare use.

Tyre upsizing is not recommended by car manufacturers as it negatively affects the fuel economy and performance of car. However, in your case, as the size difference between the two tyres is marginal you can go for the 165/70 R14 in place of the 165/65 R14.

For Maruti Swift, you can choose tyre patterns between MRF ZVTS, Apollo Amazer and Bridgestone B290.
