nominal overall tyre diameters EA stuff

Post by steptoe » Wed Jul 22, 2015 9:16 am

185.60-13 .........552mm
195.60-13..........564mm

185.65-13.........570mm
195.65-13.........584mm

175.70-13 std issue 576mm so gives a range from 551 to 591mm ?? for permitted sizes ?
185.70-13.........590mm

175.75-13.........592mm


14"s


185.60-14...........578mm
195.60-14...........590mm
205.60-14...........602mm

175.65-14...........584mm
185.65-14...........596mm
195.65-14...........610mm

15"s

195.60-15...........615mm
195.55-15...........595mm
195.50-15...........577mm

16"

205.45-16.........590mm


17"

195.40-17..........588mm
205.40-17 .........596mm

should also add 205.50-15 when I get back to the info found them on rear of my Vortex wreck

Rego usually allows up to 15mm greater, or 25mm lesser for passenger cars with wheels this size. Wonder if the more lenient rules for 4WD allows up to 50mm more ?

Can see how 195.50.15s are a great match for the original tiny tyres :) kep authorities happy once things splained to 'em

175 * 0.65 / 25.4 * 2 + 14 = OD in inches, * 25.4 = OD in mm

>Can see how 195.50.15s are a great match for the original tiny tyres

This is what I am currently running, and I honestly can't think of a better wheel setup for on-road MY's as 15" wheels are common as mud and still cheap - 50 profile isn't that common on 15's but gives decent handling without a harsh ride. The problem with stepping up to 16's is it becomes harder to find narrow rims, so it becomes 205 (borderline for a 7" rim, stretched on an 8" rim) or 215, which means instead of dropping to 45 profile it needs to be 215/40R16 which is quite expensive and also not at all common (from memory Bridgestone don't do anything at all in this size, and only a handful of other companies support it).
1989 Brumby - Shiny new red paint, stroked EJ20 phase 2 SOHC with Darton sleeves bored to EJ22, Wiseco high-compression pistons, Delta 2000 grind cams , EJ/XT6 5 stud with WRX 4/2 pots, 5-speed, 86 GTS seats and so much more.

hmm, so a real step up would be 195.40.17


so many different tyre combos "these days " !!

Need to include 185.70-13 as found them in my shed, about to go on these

Image to see how they look/feel and get rid of that empty air storage space :)
