My '01 ES300 has a leak in the front, right tire. I tried looking for a nail in there last night but it was pretty dark out. I'd like to get it plugged but until then I need to fill it up once a week. Rather than going to the gas station I thought perhaps I could get one of those little machines that you can keep in the garage, or even trunk that performs the same function, possibly even plugs into the cigarette lighter so I could use it while out on the road. Does anyone have one of these?

Secondly, the tread on my tires is getting low. What tires have you guys found works well on these third gen ES's? I'm in new england so its important they work well in the snow.

Thanks!
