Hi TN,
I installed the wheels and tire yesterday. My word. What a difference. I was a little worried about the size of the tires. I decided to go with the stock Venza size tires 245/50-20. Absolutely no fitment issues. In a worst case scenario, if I were carrying 3 adults in the third row and/or heavy gear along with 3-4 bikes mounted on the hitch rack. Only then would the top of the rear tires come in contact with the wheel wells. But I that would be an extreme situation.
Lastly, I think tirerack suggestion of 245/40-20 is to thin on the sidewall. 45 series I would say is the safest route. But 50 series gives a little more cushion. And I like cushion.
Hi TN,
I pulled the trigger on a set of 20" wheels from a Venza. I have a few lingering questions before I mount tires on these wheels. Will I need an spacers??? From what little research I did, I couldn't find any fitment issue on a 2011 Sienna. I also have a set of 245/45-20 Michelin Primacy MXV4 tires on the way.
Thanks,
