Right now the car is running on 3 stock tire, which is V rating.
And by some reason, the car has a new H rating tire, same series as the stock.

Now Im planning to change the tires..
The H rating tire, on the left rear, probabily have been running for half year, it is still in good condition.

So how should I change the tire??
Should I change all the other 3 old V rating stock tire to 3 new H rating stock tire?

Is it ok to have one used for 6 months tire running with 3 new tires??

Thanks.

 

you can just change the other three but you run the risk of odd vibrations... Ideally you should do all 4 but if you can't then changing just those 3 is going to be the best route... just be aware of the fact that it could feel a bit funny at times... your H rated tires are good up to 130... the V rating is higher...

 

So basically, if you are driving under 130, running H rated and V rated tires are not bad at all??

 

I think it boils down to budget. If you can swing four new V rated tires then do so. It that hits the wallet too hard go for three H's but have all four balanced.
