double-6s 0 Posted January 27, 2006 hi all. any idea what effect putting 205/45/15s on a vr6 C would have? was just wondering if the slightly smaller side walls might tighten up the handling a bit? any thoughts much appreciated :) Quote Share this post Link to post Share on other sites
double-6s 0 Posted January 27, 2006 sorry.... and what does the number before the speed rating letter mean...... 86V, 81V etc??? Quote Share this post Link to post Share on other sites
Trig 0 Posted January 27, 2006 Number before speed rating is the load index. Shorter sidewalls will reduce your RR so your speedo will be wrong, go for 50's I reckon. Quote Share this post Link to post Share on other sites
vr6storm 0 Posted January 28, 2006 and unless your C is lowered its gonna look even more like its on stilts...........not even sure you can get 205/45's cheaply too Quote Share this post Link to post Share on other sites
double-6s 0 Posted January 28, 2006 yeah you can. 50 quid for toyo T1-R isn't too bad. from mytyres. but they are 81V instead of the usual 86V. so does that mean they can take less loading? confused.... C is gonna be lowered real soon :) Quote Share this post Link to post Share on other sites
double-6s 0 Posted January 28, 2006 triggermyson, not too arsed about the speedo being out. i have gps which is similarly (in)accurate as the original speedo reading anyway. and wouldn't a smaller circumference mean slightly better acceleration??

NickRStorm 0 Posted January 28, 2006 http://www.toyo.co.uk/index.php?fuseaction=car.t1-r would seem to suggest that the speedo would be about 4% fast. 215/45 might be a better choice? Quote Share this post Link to post Share on other sites
double-6s 0 Posted January 28, 2006 but would i get a 215 on the standard 15 inch speedline??? they're only 6.5 inches or so wide aren't they? Quote Share this post Link to post Share on other sites
Trig 0 Posted January 28, 2006 LI of 81 equates to 462KG (per tyre) IIRC VR6 weighs about 1200KG so unless you've got a big family that should be fine! Oh and take a look at this: http://www.miata.net/garage/tirecalc.html Quote Share this post Link to post Share on other sites
NickRStorm 0 Posted January 28, 2006 but would i get a 215 on the standard 15 inch speedline??? they're only 6.5 inches or so wide aren't they? Shouldn't be a problem. I've got 215/40 x 16 on 6.5J RX2's and they're fine. Quote Share this post Link to post Share on other sites
Kevin Bacon 5 Posted January 28, 2006 I wasn't happy with 215/40/16s (7.5J wheel) as they looked lost in the arches and the ride wasn't too impressive either. Replaced them with 205/45/16 Uniroyal Rainsports and they're fat tyres, so looked chunkier than the 215s anyway, plus they're very light tyres, reducing unsprung weight and MUCH better ride quality. Improvements all round :-) Double 6s, stick with the 205/50s mate.... you will need to alter the final drive to get better acceleration ;-) Quote Share this post Link to post Share on other sites
double-6s 0 Posted January 29, 2006 still waiting for a suitable FD and pinion mate. the fella in rome had a perfect set but his mate dropped it on the way into the box to be posted to me! it broke :( Quote Share this post Link to post Share on other sites
dr_mat 0 Posted January 30, 2006 You can get the Toyo T1-Rs in 205/50/15 aswell - and they're rated 89V, so no loading problems either. Quote Share this post Link to post Share on other sites
double-6s 0 Posted January 30, 2006 thanks everyone. gonna go get some now. i obviously need aligning too, as i have a nice bald inner on my front left tyre! actually, i guess i should wait to get the alignment etc done, as i'm just about to get it lowered!!!
