RE: Tyres & Gearing, 3.36 R180

[Terry Rudd]

Tom,   P195/75R14 tyres on average turn 817 times per mile, and 195/60x14 turn 894 times per mile and a bit of maths says that your gearing will be reduced by 9.4% with 60 series 14's. Some other numbers for the in between sizes:   195/70x14 = 840 rpm or -2.8% 195/65x14 = 868 rpm or -6.2%   I haven't seen a 3.36 R180 for many moons, auto 240Z? - 3.55 are plentiful.   regards Terry -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]On Behalf Of Tom Richardson Sent: Tuesday, 11 March 2003 4:49 PM To: [EMAIL PROTECTED] Subject: Tyres & Gearing, 3.36 R180 List,   If I change from 195/75 R14 to 195/60 R14 tyres on my 240K, by what percentage will this change my gearing?  I know my speedo is now innaccurate but I'm not sure by how much - it seems to be about 15%.   Also, does know how rare 3.36:1 R180's are? I believe this was the highest ratio offered (in a 240Z?).   Cheers,   Tom --membersozdat------------------------------------------------------- OZDAT Mailing List Please Note:- Send (un)subscribe requests to [EMAIL PROTECTED] Send submissions to [EMAIL PROTECTED] No unauthorised redistribution of this email http://www.ozdat.com/ozdatonline/index.htm http://www.ozdat.com/ozdatonline/listindex.html http://www.mail-archive.com/[EMAIL PROTECTED]/ --------------------------------------------------------------------- --membersozdat------------------------------------------------------- OZDAT Mailing List Please Note:- Send (un)subscribe requests to [EMAIL PROTECTED] Send submissions to [EMAIL PROTECTED] No unauthorised redistribution of this email http://www.ozdat.com/ozdatonline/index.htm http://www.ozdat.com/ozdatonline/listindex.html http://www.mail-archive.com/[EMAIL PROTECTED]/ ---------------------------------------------------------------------
