Tire recommendations? Options

[rjames]

Looking to replace my 10 year old Eagle GTs. They are 195/60/15 but seems like only 195/65/15s are available now when looking briefly. They will go on 4 lug Mahles under stock fenders. Pretty sure I couldn't get 205s under the fenders without rolling them (not interested in doing so) because it's already pretty tight on one side.

What does the 914 brain trust recommend these days?

michelin now makes a very reasonably priced 195/65x15 that we are putting on the cars. It is the exact size for keeping the speedometer reading correctly with an extra bit of width over the standard 165x15

What tire specifically?

So, many people on this forum say 195/65-15 is correct for the speedo, but my GPS testing says not. All brands in this size are right at 25” diameter which yields a 5mph fast indication error.

A 165HR15 by comparison is a 25.4” diameter, which is still shy of what you would need to make indicated = GPS actual.

A 26.5” diameter is what you need to get your speedo to read true… which is a 185VR15

according to tiresize.com 165/80/15 is 25.4 185/70 15 is 25.2 and 195/65.15 is 25.0 with a speedometer reading of minus 1.5 mph with the 195 at 90 mph or 88.6

None of that is relevant until you asses your current speedometer error via GPS.

Ex: OE tire size for my 996 C2 is 265/35R18. But a 275/40R18 gives me an exact match to GPS on my speedometer.
