Are these tires still being made in 215/45 or 225/45-17 sizes?

I just got a set of 215's online - they were manufactured in Jan of 2015, and they seem to be kind of hard to find on-line - lots of places seem to be out of stock for most sizes.

GTradial website doesn't list very many sizes (not these), and the global site only has 3 :

Global - 3 sizes :
http://www.gtradial.com/global/Tire-...s/CHAMPIRO_SX2
195/50-15, 235/45-17, 265/35-18

US - 10 sizes, 3 in 17" "

215/40-17, 235/40-17, 235/45-17

Just as a data point, I've ordered 215/45R17 SX2s from Walmart this week and just got a set with "4417" marking, i.e. manufactured in October/November of 2017.

Thanks, I was actually going to ask the same question.
Assuming the size of the contact patch is roughly proportional to the width of the thread, 31-ish psi sounds like a reasonable number for 245s?

Although I'm sure I'm missing something important here

Dumb question but do these tires matter which way they are mounted. My tires all had a blue line on the outer side of the tire so I mounted mine with this facing out rather than in closer to the wheel well.

They all have the "Outside" mark on the outside sidewall.

I've gone through a couple sets of Radial GT UHP tires and they were great. 235/45/17's for about 50 bucks apiece from Discount Tires. Unfortunately I haven't been able to find them for a few years. Looks like the SX2's should be pretty good but they cost quite a bit more.
