Hi all,

I just ended my old lease 2011 IS250 and got a new 2015 IS250 F sport AWD, and i have a set of lightly used (2 years) winter tire (22/45R17) left be hide. I noticed the tire size on the new model is different from the old model, i am just wondering is it safe to put my old winter tire on the new car? will it damage the new car?

Thanks in advance

Congrats on your new IS. Yes you can mount those 225/45/17 winters since the overall tire diameter is equivalent to the 18in stock tires, but you'll need to buy 17in steelie (cheapest) rims with a 5x114.3 pattern if the tires are not mounted on wheels. Only "negative” with these tires is the visual of the rear tire will look skinny compared to the 255/35 stock 18in tires.

Yes, the tires would fit on your new IS as this is what I am doing on mine. In fact, 225/45R17 is the standard tire size for IS as listed in the specification in your IS brochure. It is just not too obvious as it is rare to see a base IS on the road.

However, you may get slight vibration because the tires were on a different car. But since you mentioned the tires were lightly used, it doesn't hurt to try on the new IS.

Just as CorradoMR2 said, the 17" would look a bit small and skinny especially the rear ones.

Not sure, but I think when you go to a AWD car, steelies are not ideal, and you should use alloy wheels. Others can chime in here, but my understanding is the added torque from the AWD system requires alloy.

Bunk; steelies aren't a problem, they're stronger than cast and may even be lighter weight or at least better rotational mass distribution.

Also you forgot to mention how great his new ride will look with those steelies.

Hi all. I was reviewing my IS250 owner manual to see the tire sizes it rexommands. In the tire and wheel section. It said something like type A,B...E. What does these types mean?
