Tires: Nissan Quest tire size change, speed capability, nissan quest
QuestionI have a 2004 Nissan Quest that calls for a 225-65R-16 H rated tire. the choices for this tire are extremely limited to say the least. The Original tire barely lasted 30k miles. Is it unsafe to drop to a 215-65-16 T rated tire?
AnswerJim,
This is not a good direction to go.
First, you would be going down in load carrying capacity, and second, you would be going down in speed capability. This is a double hit in capability and these types of changes increase the probability of a tire failure.
I'd recommend you look at 215/70R16's, which is at least the same load carrying capacity. But as a word of caution, if you exceed 75 mph, you ought to stay with the H speed rating.
