Help requested! Ride on new snow tires.

Greetings! I own a 2010 Higlander base V6 model which came with Toyo A20 Open Country P245-65-17 tires. Very nice ride indeed, even bumpy road sections were barely felt.



Because I live in Canada I wanted some good winter tires. Bought a set of wheels, same size (17X7.5, 5 on 114.3 with 35 offset) and after much research bought a set of Hankook i-Pike RW ll tires P245-65-17. Had the tires on for two weeks now and the ride is terrible, it's almost as though I have no shocks at all! I feel every bump in the road. Nice tires and virtually no road noise - but the ride. I measured the height of the Hankook and saw that it is 3/4 inch less in height than the original Toyo's. Should I have installed P245-70-17 tires possibly to gain the extra height and and perhaps a better ride. I do not know what height the 70 has over the 65 and if the height may be too close to a shock - but am going to find out. The ride is just awful. I am also wondering if I do change to the 70 height would I void my Toyota warranty?



I really appreciate help on this problem.

Out of curiosity...have you checked/adjusted the air pressure in your 'new' tires? Sounds like they're a bit over inflated. Before you go nuts, start with that. Use the pressure rating (usually 32 PSI) that's listed on the placard in the drivers side door way.

Thank you for your comment MikeyD25. Yes, the tire pressure is set correctly at 30psi on all 4 tires as per the door label setting. Nice tread pattern,very quiet tires but a real bumpy ride.
