Bear in mind all 70 series are fairly hard on tyres, so you'll want a fairly
hard compound else you'll be replacing the front ones every year...!
I run Pirelli P6000's on our 98 S70 2.5 10v manual at 33psi F and 30psi R
(abit above book) which does make the ride slightly more jittery and alittle
louder than stock but I get 2mpg more and they're doing around 20-22k when
swapped front to back at about 15k miles, which i consider excellant.
Grip is very good in the dry, and good in the wet.
Note I have the T5 spec 205/50 16 inch alloys which does impact ride comfort
somewhat.
The previous 850 we had ran on your size rims initially had some goodyear
nct5's which were grippy and quiet, but only lasted 9000 miles! Pirelli's
went on that then.
