1st posted this back in Mar of '09 before My '90 Westy 2wd4mt had been Subarued > ORRs 2cents on tires & revs & MPGs --> I'm running 205/65R15s on the front to keep the same 25.5in Dia' as orig' & 235/75R15s / 28.9in Dia on the rear to get the RPMs down & MPGs up. I get 70mph @ 3500rpm & 20-22mpg with the Orig' 2.1L MT4 in my 90Westy. ORR ~ DeanB
In 2010, a few mo's after it Became VDubaru, I replaced the Orig' 0.85 4th Gear with a 0.77 & now I get 70mph @ 3150rpm ~ On 18 Oct , 2018, at 8:42 AM, Don Hanson wrote: > I'm about due for more tires and I've spotted some appropriate 16" wheels > at a good price.
