Rackers Posted July 16, 2012 Report Share Posted July 16, 2012 Hi All, Wanted some new tyres for the front (Uniroyal Rainsport 2) but have just found out I'm currently running 215/40/R17 but the Gen 7 should have 215/45/R17. My question is does having the 45 profile make a HUGE difference? If so looks like I'll be getting 4 new tyres as I am assuming you can't run 215/45/R17 on the front and 215/40/R17 on the rears? Thanks Link to comment Share on other sites More sharing options...
arizona Posted July 16, 2012 Report Share Posted July 16, 2012 (edited) You could run 40's on the front and 45's on the rear and then get the 40's replaced later with 45's when they need changing Difference i found is that the ride is better, smoother with 45's Edited July 16, 2012 by arizona Link to comment Share on other sites More sharing options...
sadlebag Posted July 16, 2012 Report Share Posted July 16, 2012 yeah 45's so much better. Link to comment Share on other sites More sharing options...
Gstraw Posted July 16, 2012 Report Share Posted July 16, 2012 you can run different on each axle. i done that for a year and now have 45 all around. don't change good tyres tho- use them up and hang fire Link to comment Share on other sites More sharing options...
Rackers Posted July 16, 2012 Author Report Share Posted July 16, 2012 Might get some Vredestein Ultrac Sessanta in that case then, they don't do them in a 45 so might save me the trouble in the mean time? Link to comment Share on other sites More sharing options...
Rackers Posted July 16, 2012 Author Report Share Posted July 16, 2012 Anybody gone from 45 to 40s and noticed a huge difference? Thanks! Link to comment Share on other sites More sharing options...
tom ato Posted July 17, 2012 Report Share Posted July 17, 2012 Yer I got 45 on my tsports and they are a lot better than the40s that they had on when I got them And look better not too low profile Link to comment Share on other sites More sharing options...
Kev 16v Posted July 17, 2012 Report Share Posted July 17, 2012 Anybody gone from 45 to 40s and noticed a huge difference? Thanks! The Gen 7 should have 205/45/17. You would notice a difference in acceleration as the two sizes you mention are either side of 205/45 as regards rolling radius. If you don't mind a slower 0-60, the 215/45 will offer more comfort as mentioned above, and fill the arches a little better. As Arizona mentioned, unless you have a face lift TS or GT, you could run the larger profile on the rear, which is exactly what I do. Link to comment Share on other sites More sharing options...
celicamojo Posted July 17, 2012 Report Share Posted July 17, 2012 Anybody gone from 45 to 40s and noticed a huge difference? Thanks! I have 40's on the current wheels, had 45's on the previous ones. The ride is noticably harsher on 40's and as I live in Scotland, every journey involves potholes. have buckled 2 wheels recently. getting them fixed next week and will be shod in new 215 45 17 rubbers. 40's do look cool, but car also sits too low for the numerous speedhumps around here, seem to remember a calculation of 7mm lower.... its a toss up between cool and bank balance!!

Rackers Posted July 17, 2012 Author Report Share Posted July 17, 2012 Gone for 45s all round, have to admit I'm fed up with the harsh ride my 40s have given me. Link to comment Share on other sites More sharing options...
rich_p Posted July 18, 2012 Report Share Posted July 18, 2012 Does anyone have pictures of how 215/40 vs 215/45 look? I'm looking getting some 17x8 wheels and know that standard 205/45 isn't an option. Does anyone have pictures of how 215/40 vs 215/45 look?

arizona Posted July 18, 2012 Report Share Posted July 18, 2012 (edited) the 45's will also give the effect of filling the arches better and 215 gives your rims a bit more protection makes of tyres vary as to whats available but 215/45 would be my first choice , failing that 205/45 is perfectly fine tbh i doubt you'll notice much difference with the drive. EDITED - Hadnt read post properly 8's i'd missed, ignore what i said 225 or 215 i believe - but still 45's better Edited July 18, 2012 by arizona Link to comment Share on other sites More sharing options...

rich_p Posted July 19, 2012 Report Share Posted July 19, 2012 215 is minimum width, this should provide minimum if any stretch. I'm sure I've seen pictures of this setup on a Celica, and it looked perfectly normal. You are correct in saying 225 would be ideal though. I confess I've not looked at what is available to get close to a stock rolling radius or if there would be any rubbing issues with the extra width. http://www.tyres-pneus-online.co.uk/equivalency-tables-advice.html Link to comment Share on other sites More sharing options...
